I made some style changes to em-hist.el and registered that commit in the new .git-blame-ignore-revs file to preserve blame data of other commits. The single-clause if statements frequently throw me off, so I think it's worth removing them now that there's a way to do so without ruining git blame sessions.
I signed an FSF copyright assignment about a year ago when I submitted something to the Emacs package Ivy. Attached are the files they sent me confirming successful registration. If I need to send something else instead, please let me know.
Thanks,
Brian

Subject: [PATCH 1/2] eshell/em-hist: Style and indentation cleanup
* lisp/eshell/em-hist.el: Use spaces over tabs, when over
single-clause if, and more consistent indentation.

Subject: [PATCH 2/2] Add .git-blame-ignore-revs
Git 2.23 introduced the ability to ignore certain revisions during git
blame. We can thus freely make changes to style and indentation while
preserving blame data.

You've configured emacs to replace TAB with SPC. Please donʼt do that,
it makes it very hard to figure out what you've actually changed.

That's what our .dir-locals.el does, doesn't it?

Only for lines that you change. The patch has wholesale TAB->SPC
replacement for lines which haven't otherwise been modified.

Right.
In that case, we should probably clarify that we don't usually
whitespace-only changes far from the code that's being changes.
Do we accept reindentation patches, though? Ones where the effective
indentation does change.

Didnʼt we just have this thread? :-)
Pure re-indentation patches I thought were not acceptable unless
accompanied by an actual code change near the re-indented lines.

Okay.
Brian, could you re-submit patches without extra re-indentation?

OK, please see attached. Right now there are no extraneous whitespace changes, and the only changes I've made change if -> when in the eshell files.

With a .git-blame-ignore file of some sort, shouldn't this not be a hindrance?

I'm not sure I understand the rationale: why would we want to replace
all 'if's with 'when's? Was that discussed, here or elsewhere? if so,
could someone point me to that discussion?
Thanks.

I expected that people would find it easier to read 'when'/'unless' than single-clause 'if' statements. The 'when'/'unless', along with the indentation of the corresponding 'then' clause, immediately signal that there is only one possible non-nil form returned. With single-clause 'if' statements, you would have to continue reading past the 'then' clause to spot what the 'when'/'unless' and its differing indentation immediately tell you.

To go over two dozen of files and summarily replace 'if' with 'when'
for this reason sounds way too radical to me. I have no difficulties
understanding the original code, FWIW.
Is it just me? do others think such changes are a good idea?

I hate one-form-`if' more than anybody, but I don't think these purely
stylistic rewrites are a good idea, as it means that "git blame" and
vc-region-history gets less useful, and applying older patches fails
more often.

OK, I won't submit that commit then. The other commit I had introduced a .git-blame-ignore-revs file, which allows certain commits to be ignored during git-blame sessions. I've modified that commit accordingly and attached. Would that be of use?
My FSF papers are attached.

I think this sounds very useful. And it works well in practice from my
limited testing.
Does anyone object to adding this file?

I don't think I understand what does this file mean from the
maintenance POV. Who will maintain it, and what are the procedures?
And what should be done about it while merging from the release branch
to master?

I would propose that we treat it as an optional feature rather than
striving for it to include a complete list of all "uninteresting"
commits at all times.
Even if it were to include only a proportion of some of the latest
"uninteresting" cleanups, that could already be of help. When someone
stumbles into a commit that gets in the way of their git blaming they
could also consider adding it.

I don't think anything in particular needs doing, since the sha-1 will
stay the same after a merge. Or am I missing something?

We already mark such commits with a leading semi-colon. Will this
file simply repeat those commits?

Not all of the commits get merged. Some are skipped.

Yes, if we want the commits ignored by "git blame". But of course it
could include only some of them, as well as commits not marked with a
leading semi-colon.

Wouldn't having non-existent commit ids in there mostly be an aesthetic
problem?

Why would someone want to skip commits in "git blame"? We need to
have agreed-upon criteria or policy for that, otherwise each one of
use will step on the others' toes. "git blame" is an important
forensics command, so hiding commits from it might surprise someone,
if it's unexpected.

I don't know. Will it? I have no experience with this feature.

For example, if a commit fixed a typo in a doc string, I'd much rather
see the commit that added that text than the one that fixed the typo.

AFAIU, git will just skip over non-existent commits in this case.

But that's your personal preference, isn't it? Do we know for sure no
one will ever want to see changes that fixed typos? For example, what
about some "typo" that is controversial (like the "parseable" thing we
discussed lately), and we want to know who and why "fixed" it?
In short, the more I think about this feature, the less it makes sense
to me to use it in our project. It's probably fine for a
single-developer projects, where the preferences are never in
conflict. But ours is a very different project.

It requires a setting in .git/config, doesn't it? Would older
versions of Git warn about the setting they don't know about? Or do
we expect users to turn this on in their ~/.gitconfig instead?

I think I'd want commits like that included in git blame...

If Emacs was a project that did extensive "janitorial" fixups, then it
might make more sense. For instance, if we were to fix all whitespace
to be consistent, then having a way to ignore that would be nice. But
we don't, so I'm not sure adding a .git-blame-ignore-revs file helps us
much.
The only thing I'd want to use such a file for would be for things that
really are 100% non-functional: Whitespace changes and spelling fixes
for comments.
So I don't think such a file would help the Emacs project.

You both make good points.
I guess the logical conclusion here is to close this bug as wontfix.

No further comments within 20 weeks, so I'm closing this as wontfix.
