Hello,

How about a prefix argument to vc-prepare-patch to invert one's usual
setting for vc-prepare-patches-separately?  Most people who contribute
to more than one project regularly will want to use both.

On the other hand, having a numeric prefix argument mean "send patches
correspoding to the top N revisions of the current branch" would be very
convenient.  Perhaps these two could be combined by using a negative
number to mean also invert?

How would this be preferable to setting `vc-prepare-patches-separately'
as a directory local variable?  That way you don't have to remember to
use a prefix argument whenever invoking `vc-prepare-patch'.

This is the usual problem with numeric prefix arguments.  You don't get
that much expressivity with just an integer.

That is why I would hesitate to assign any particular interpretation to
prefix arguments, before considering and weighing the options.

I was wondering if you had any comments on my last message:

Well, any other options in mind?  Varying the -N argument to
git-format-patch/git-send-email is what I find myself using the most.

The issue is finding a way for this to be expressed VC-generically.

I meant expressed, but I don't remember what I meant ^^

So let's say implement.  What we could do is just call
`previous-revision' for the backend N times, but with what file?

I don't know, but the meaning of "the past N checked-in revisions of the
whole tree" is what we need to agree upon, then it's just coding.

The critical edge-case here is what happens when branches are merged.
Do you pick a random branch or collect all the patches.  Or do you raise
an error, but then how do you detect that vc-generically.

Typically you wouldn't want to format patches across a merge, so I would
suggest raising an error.

And this is something I don't think can be /expressed/ using vc, because
while I can collect a number of revisions using `previous-revision',
there is no general way to verify if a commit is a merge commit.

Can we do that part on a VCS-by-VCS basis?  Default to just calling
previous-revision and hoping for the best, but giving vc-git.el a chance
to raise an error.

I guess that would be possible, though it will probably require a new
VC method :/  The new `prepare-patch' takes a revision, so it doesn't
make sense to pass it a number and have it return multiple patches.

Perhaps it will be easier/cleaner to just accept that avoiding merge
revisions is the users responsibility.

But just to have mentioned it:  Do you know that you can mark revisions
in log-view and then vc-prepare-patches will use these as the default
input when prompting for revisions?

Please don't forget that Git's notion and implementation of
merge-commits is (AFAIR) quite unique.  I'm not sure there's another
VCS which handles merge-commits like Git does.

So when you build your notion of what merge-commit is and how to deal
with it in the context of this issue, I think it is best to study what
the other VCSes do, before you base the design on what Git does.

Sounds reasonable -- it can always be enhanced later in a way that's
backwards-compatible.

Yeah, but marking in those buffers is way more awkward than marking in,
e.g., dired, and I usually know how many commits I want to send without
looking at the log.

Thanks, and the same with package-vc-prepare-patch, please?

Btw, this kind of reformatting:

> -PKG must be a package description.
> -Interactively, prompt for PKG, SUBJECT, and REVISIONS.  However,

is IMO for the worse: when the sentence starting with "Interactively"
begins a new line, it stands out, which helps users find the most
relevant parts faster.

That being said, the patch now relies on changes made in
scratch/package-vc-fixes.  I can "backport" it onto master, or push it
in a few days when the issues related to that branch are resolved.

Great, I'll close the issue then.  The patch will be pushed along with
some package-vc related changes in the next new days.
