The new determine_author_info() should fix this. There was a problem
earlier that Junio pointed out and I sent a patch to update
determine_author_info() to do the right thing for amend commits. The
test suite still pass without this patch, and if you look carefully a
determine_author_info(), you can see it does the right thing:
1) Default to getenv for name, email and date
2) If a commit has been specified (-c, -C or --amend), we parse the
author name, email and date from use_message_buffer, which holds the
commit, overriding the values from getenv.
3) If --author has be passed, we parse name and email from the
argument and override whatever name and email the two previous steps
came up with.
Then we add the author line to the commit buffer under construction
based on these values.
I suggest we back this patch out.
cheers,
