I am slightly worried that we do not unset this environment variable (or
revert to its previous value, if it had any).
I had a brief look and it seems that there are only two callers of
`commit_tree_extended()` (which uses `git_committer_info(IDENT_STRICT)` to
fill in the committer date), so it _should_ be possible to extend the
signature of `commit_tree_extended()` to specify the committer information
explicitly.
The bigger question is whether we _actually_ need this, and I _think_ that
the answer is "not right now", so I would be fine with the patch as-is.
Just thought that I point it out (and thereby demonstrate that I actually
looked at the patch ;-)).
Ciao,
