Should the old one be dropped? Or is moving the new text a leftover mistake from rebasing (IIRC, in your original you dropped this whole "here's how commits work" section). Other than that, the patch looks good to me. -Peff

Thanks for pointing this out. I'll fix it and if nobody else has comments today, send out a v5 later this week, probably tomorrow.

This is copied from the end of the "commit information" section, without the original getting removed (see the post-context of the hunk that begins at l.79/l.82). Intended? I haven't seen anybody use the phrase "commit comment" in the reviews on this list for long time; the phrase somehow feels outdated. The pretty formats section in "git log --help" calls this "commit message". "log message" may also be more common. > @@ -69,7 +73,6 @@ OPTIONS > Do not GPG-sign commit, to countermand a `--gpg-sign` option > given earlier on the command line. > > - > Commit Information > ------------------ > > @@ -79,26 +82,6 @@ A commit encapsulates: > - author name, email and date > - committer name and email and the commit time. > > -While parent object ids are provided on the command line, author and > -... > -that file does not exist). > - > A commit comment is read from stdin.

Ah, you spotted the same thing.

Git Diffs ~~~~~~~~~
While at one time it made perfect sense to store information about configuring author and committer information in the documentation for git commit-tree, in modern Git that operation is seldom used. Most users will use git commit and expect to find comprehensive documentation about its use in the manual page for that command. Considering that there is significant confusion about how one is to use the user.name and user.email variables, let's put as much documentation as possible into an obvious place where users will be more likely to find it. In addition, expand the environment variables section to describe their use more fully. Even though we now describe all of the options there and in the configuration settings documentation, preserve the existing text in git-commit.txt so that people can easily reason about the ordering of the various options they can use. Explain the use of the author.* and committer.* options as well.
