Based on the discussion it sounds like there are complications to
supporting relative paths (due to worktree config), and "$HOME"
(when generalized, due to bootstrapping issues with $GIT_*).

I think that is fine for now. One other simple possibility would be to
expand _just_ $HOME, and then if we later decided to do all environment
variables it would naturally encompass that. However, we might want to
support "~" then anyway, so I think doing "~" first is fine.

However, there are two problems with the patch:

  1. It should probably re-use path.c:user_path, as Johannes mentioned.

  2. There is no documentation update.

Also, are there any other config variables which would benefit from this
substitution (I can't think of any off-hand, but there are quite a few I
don't use).
