Eric made me do it :). Personally I prefer the non-ambiguous "directory"
over "path". In fact, "directory" is used in the error message spat out
by git:
$ git --work-tree
No directory given for --work-tree.
...
$ git --git-dir
No directory given for --git-dir.
...
$
I think changing "<path>" to "<directory>" wherever appropriate in
git.txt would be an improvement. Tangent: <dir> is shorter but that
might not be easy on the translators.

No it doesn't. I'll fix it in the next reroll.

I agree with you here. I'll send the reroll later.
