[PATCH] git-send-email: default value for "From:" field.

[Quy Tonthat <qtonthat@gmail.com>]

If user hits enter at the prompt for
"Who should the emails appear to be from?",
the value for "From:" field was emptied instead of GIT_COMMITER_IDENT.

It seems the original code assumes readline to accept
an extra argument for default value. I don't remember I ever encountered
that feature from readline. Is there anything like that out there ?
