After committing, I often want to return to the place of the latest
change to continue my work. Add the new mode "commit" which does exactly
this.

Optional arguments are given to the "git show" call. So it's possible to
jump to changes of other commits than HEAD.

That's one of my primary uses for git-jump, too. But you can already do
that by jumping to the diff of HEAD^. Which has the additional advantage
that it's a diff against the working tree. So if you did a partial
commit, the diff will include any leftover changes.

So I'm not opposed to this patch per se, given that it's not very many
lines. But I'm not sure I see much advantage over "git jump diff HEAD^".
It's slightly less typing, but I already alias "git jump diff" since
it's so long.

This can also be done with "git jump diff $commit^ $commit". However,
I've found that jumping based on older diffs is mostly useless, because
the line numbers at $commit and those in the working tree don't always
match up (and inherently you're always jumping in the working tree
copy).

Thanks, I didn't realize that git diff could just as well be used to
generate the diff of an arbitrary commit. I have added this new shortcut
to my bash aliases:

    gjc() { git jump diff ${1:-HEAD}^ ${1:-HEAD}; }


Cheers, Beat
