[PATCH] blame: Improve parsing for emails with spaces

[Josh Stone <jistone@redhat.com>]

One of my git repositories has some old commits where the authors
obfuscated their email address as <author at example dot com>.  To
handle this, blame needs to look for the leading '<' when scanning
to split the "name <email>", rather then only a space delimiter.
