Subject: git-diff.txt: reorder possible usages
X-Git-Tag: v2.28.0-rc1~4^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=78b76d310f3e9c0cc1e990ed93f58711e48d9ab2;p=thirdparty%2Fgit.git

git-diff.txt: reorder possible usages

The description of `git diff` goes through several different invocations
(numbering added by me):

  1. git diff [<options>] [--] [<path>...]
  2. git diff [<options>] --no-index [--] <path> <path>
  3. git diff [<options>] --cached [<commit>] [--] [<path>...]
  4. git diff [<options>] <commit> [--] [<path>...]
  5. git diff [<options>] <commit> <commit> [--] [<path>...]
  6. git diff [<options>] <commit>..<commit> [--] [<path>...]
  7. git diff [<options>] <commit> <commit>... <commit> [--] [<path>...]
  8. git diff [<options>] <commit>...<commit> [--] [<path>...]

It then goes on to say that "all of the <commit> in the above
description, except in the last two forms that use '..' notations, can
be any <tree>". The "last two" actually refers to 6 and 8. This got out
of sync in commit b7e10b2ca2 ("Documentation: usage for diff combined
commits", 2020-06-12) which added item 7 to the mix.

As a further complication, after b7e10b2ca2 we also have some potential
confusion around "the '..' notation". The "..[.]" in items 6 and 8 are
part of the rev notation, whereas the "..." in item 7 is manpage
language for "one or more".

Move item 6 down, i.e., to between 7 and 8, to restore the ordering.
Because 6 refers to 5 ("synonymous to the previous form") we need to
tweak the language a bit.

An added bonus of this commit is that we're trying to steer users away
from `git diff <commit>..<commit>` and moving it further down probably
doesn't hurt.
