Severity: minor
The docstring of `progress-reporter-update' contains the following text:
If REPORTER is a numerical progress reporter---i.e. if it was
made using non-nil MIN-VALUE and MAX-VALUE arguments to
`make-progress-reporter'---then VALUE should be a number between
MIN-VALUE and MAX-VALUE.
If I place point on the space after "i.e." on the first row, and type
C-M-b (backward-sexp), point ends up before "reporter". (This happens
in `emacs-lisp-mode', but not in `message-mode'; `message-mode' seems to
have no concept of an abbreviation and lands on the "e".)
This in turn leads to checkdoc flagging this as a mistake, and asks you
to put two spaces after dot.
I'm not sure which of these options is true:
A) We should support the above convention of using three dashes in
`backward-sexp'. (This is the rough ASCII equivalent of an em dash.)
B) We should just not use the above convention in
`progress-reporter-update'.

Why does it do that? because it doesn't recognize "i.e." as something
that doesn't end a sentence? And if so, how does the "---" thing come
into play here?

None of the above? I guess I don't yet understand the root cause for
the problem.

I guess I have mixed up two different things above.
From my point of view, the first thing to do is to decide is if this
`backward-sexp' behavior is a bug or not. So this comes down to if we
think that "---" should be treated as a delimiter, just as " - " is, in
the context of ELisp docstrings.
I don't have a strong opinion either way, but I did find the current
behavior somewhat surprising when I saw it.
On the other hand, even if this is a bug, it might very well not be
worth fixing as the "---" delimiter is not very commonly used.

How do we decide? What is TRT for backward-sexp in context that has
no sexps? If we change anything here, it could potentially affect a
lot of unrelated code out there.
Once again, why does checkdoc want you to have 2 spaces there? what
rule is it that ends up requiring that?

That's true.

Sorry, I didn't understand you were asking about checkdoc. The code
there is really simple: find the next dot (that is also at a word
boundary), run `backward-sexp', use a regexp to see if this is an
abbreviation.
So it lands on the "r" in "reporter---i.e." and says, no, this is not an
abbreviation I know about, so there has to be two spaces after the dot.

Because you said:

> to put two spaces after dot.
I read this as the issue you'd like to solve: to prevent checkdoc from
flagging this as a mistake. Was I misinterpreting your report?

Isn't _that_ a bug, right there? Why does checkdoc use this strange
strategy for identifying abbreviations? A punctuation character that
precedes an abbreviation shouldn't interfere with recognizing the
abbreviation, IMO. And using sexp movements in text that is not
really a sexp is perhaps "the original sin" here?
IOW, I see no reason whatsoever to believe backward-sexp is the
problem here. The problem is in checkdoc, and IMO should be solved
there.

No, I guess this bug report touched on several different things is all.
It seems productive to focus the discussion on checkdoc as you suggest.

True. I guess it makes sense to just use 'backward-word' instead.
Unless anyone has any better suggestions, I will try this approach and
see how well it works in practice.

This has now been fixed by using 'forward-word' instead of
'forward-sexp' in checkdoc (commit 55083d90a3). I also added three new
test cases.
I'm therefore closing this bug report.

I think the ---s here should just be made into parentheses.

That would be the easiest option by far. Maybe that's all we need to do
here, really.
