Subject: git-svn: allow empty email-address using authors-prog and authors-file
X-Git-Tag: v2.18.0-rc0~135^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/cb427e9eb0243fe7a1a22ea3bd0a46b7410c0bf3?hp=cb427e9eb0243fe7a1a22ea3bd0a46b7410c0bf3

git-svn: allow empty email-address using authors-prog and authors-file

The email address in --authors-file and --authors-prog can be empty but
git-svn translated it into a fictional email address in the form

jondoe <jondoe@6aafaa21e0fb4338a68ab372a049893d>

containing the SVN repository UUID. Now git-svn behaves like git-commit:
If the email is *explicitly* set to the empty string using '<>', the
commit does not contain an email address, only the name:

jondoe <>

Allowing to remove the email address *intentionally* prevents automatic
systems from sending emails to those fictional addresses and avoids
cluttering the log output with unnecessary stuff.
