git-svn: parse authors file more leniently
Currently, git-svn parses an authors file using the perl regex /^(.+?|\(no author\))\s*=\s*(.+?)\s*<(.+)>\s*$/ in order to extract svn user name, real name and e-mail. This does not match an empty e-mail field like "<>". On the other hand, the output of an authors-prog is parsed with the perl regex /^\s*(.+?)\s*<(.*)>\s*$/ in order to extract real name and e-mail. So, specifying a trivial file grep such as grep "$1" /tmp/authors | head -n 1 | cut -d'=' -f2 | cut -c'2-' as the authors prog gives different results compared to specifying /tmp/authors as the authors file directly. Instead, make git svn uses the perl regex /^(.+?|\(no author\))\s*=\s*(.+?)\s*<(.*)>\s*$/ for parsing the authors file so that the same (slightly more lenient) regex is used in both cases.
