In gitsubmodules.txt, a few non-ASCII apostrophes are used to spell
possessive, e.g. "submodule's".  These unfortunately are not
rendered at https://git-scm.com/docs/gitsubmodules

 correctly by the
renderer used there.

Use ASCII apostrophes instead to work around the problem.  It also
is good to be consistent, as there are possessives spelled with
ASCII apostrophes.

This was an undocumented debugging aid that does not seem to
have come in handy in the past decade, judging from its lack
of mentions on the mailing list.

Let's drop it in the name of simplicity. This is morally a
revert of 3131b713 (Add "--show-all" revision walker flag
for debugging, 2008-02-09), but note that I did leave in the
mapping of UNINTERESTING to "^" in get_revision_mark(). I
don't think this would be possible to trigger with the
current code, but it's the only sensible marker.

We'll skip the usual deprecation period because this was
explicitly a debugging aid that was never documented.

The "--show-all" revision option shows UNINTERESTING
commits. Some of these commits may be unparsed when we try
to show them (since we may or may not need to walk their
parents to fulfill the request).

Commit 3131b713 (Add "--show-all" revision walker flag for
debugging, 2008-02-09) resolved this by just skipping
pretty-printing for commits without their object contents
cached, saying:

  Because we now end up listing commits we may not even have been parsed
  at all "show_log" and "show_commit" need to protect against commits
  that don't have a commit buffer entry.

That was the easy fix to avoid the pretty-printer segfaulting,
but:

  1. It doesn't work for all formats. E.g., --oneline
     prints the oid for each such commit but not a trailing
     newline, leading to jumbled output.

  2. It only affects some commits, depending on whether we
     happened to parse them or not (so if they were at the
     tip of an UNINTERESTING starting point, or if we
     happened to traverse over them, you'd see more data).

  3. It unncessarily ties the decision to show the verbose
     header to whether the commit buffer was cached. That
     makes it harder to change the logic around caching
     (e.g., if we could traverse without actually loading
     the full commit objects).

These days it's safe to feed such a commit to the
pretty-print code. Since be5c9fb9 (logmsg_reencode: lazily
load missing commit buffers, 2013-01-26), we'll load it on
demand in such a case. So let's just always show the verbose
headers.

This does change the behavior of plumbing, but:

  a. The --show-all option was explicitly introduced as a
     debugging aid, and was never documented (and has rarely
     even been mentioned on the list by git devs).

  b. Avoiding the commits was already not deterministic due
     to (2) above. So the caller might have seen full
     headers for these commits anyway, and would need to be
     prepared for it.
