I'm puzzled. GIT should handle this fine.

	export GIT_AUTHOR_NAME=''
	git-commit-tree $(cg-object-id -t)

works as expected, but for some reason escaping me it does not work
inside of cg-commit. Insights welcomed.

Thanks, I've updated the cg-commit version. Note that the empty
GIT_AUTHOR_NAME problem seems to exist in git-commit as well.

It depends on what you expect, but it meets _my_ expectation:

    $ GIT_AUTHOR_NAME='' git-commit-tree $(git-write-tree) </dev/null

    committer Junio C Hamano [off-list ref] 1139281078 -0800

That is, the user said GIT_AUTHOR_NAME is empty, so he gets a
commit with an empty author name.

get_ident() in ident.c does this. getenv("GIT_AUTHOR_NAME") and
friends are passed to it, and git_default_* are takenfrom gecos.
It might match some peoples' expectation (but not mine) if we
did this instead.
