Based on its name, people may read the 'git revert' documentation when
they want to undo local changes, especially people who have used other
SCM's.  'git revert' may not be what they had in mind, but git
provides several other ways to undo changes to files.  We can help
them by pointing them towards the git commands that do what they might
want to do.

If 'make install' was run with sufficient privileges, then the installed
templates, which are copied using 'tar', would receive the user and group
of whoever built git. This instructs 'tar' to ignore the user and group
that are recorded in the archive.

"git-merge" is a binary executable these days, and looking for assignment
to $all_strategies variable with grep/sed does not work well.

When asked for an unknown strategy, pre-1.6.0 and post-1.6.0 "git merge"
commands respectively say:

    $ $HOME/git-snap-v1.5.6.5/bin/git merge -s help
    available strategies are: recur recursive octopus resolve stupid ours subtree
    $ $HOME/git-snap-v1.6.0/bin/git merge -s help
    Could not find merge strategy 'help'.
    Available strategies are: recursive octopus resolve ours subtree.

both on their standard error stream.  We can use this to learn what
strategies are supported.

The sed script is written in such a way that it catches both old and new
message styles ("Available" vs "available", and the full stop at the end).
It also allows future versions of "git merge" to line-wrap the list of
strategies, and add extra comments, like this:

    $ $HOME/git-snap-v1.6.1/bin/git merge -s help
    Could not find merge strategy 'help'.
    Available strategies are: blame recursive octopus resolve ours
    subtree.
    Also you have custom strategies: theirs

    Make sure you spell strategy names correctly.

We don't actually modify the struct object, so there is no
reason not to accept const versions (and this allows other

The code remembered that the last diff output it saw was an empty line,
and tried to reset that state whenever it sees a context line, a non-blank
new line, or a new hunk.  However, this codepath asks the underlying diff
engine to feed diff without any context, and the "just saw an empty line"
state was not reset if you added a new blank line in the last hunk of your
patch, even if it is not the last line of the file.

In handle_from, we calculate the end boundary of a section
to remove from a strbuf using strcspn like this:

  el = strcspn(buf, set_of_end_boundaries);
  strbuf_remove(&sb, start, el + 1);

This works fine if "el" is the offset of the boundary
character, meaning we remove up to and including that
character. But if the end boundary didn't match (that is, we
hit the end of the string as the boundary instead) then we
want just "el". Asking for "el+1" caught an out-of-bounds
assertion in the strbuf library.

This manifested itself when we got a 'From' header that had
just an email address with nothing else in it (the end of
the string was the end of the address, rather than, e.g., a
trailing '>' character), causing git-mailinfo to barf.

GNU diff's --suppress-blank-empty option makes it so that diff no
longer outputs trailing white space unless the input data has it.
With this option, empty context lines are now empty also in diff -u output.
Before, they would have a single trailing space.

   (git_diff_basic_config): Set it.
