[PATCH RFC] gitweb: Handle non-ASCII email addresses

Hi!

I accidentally had a bad user.email setting ("jbglaw@ług-owl.de" instead of "jbglaw@lug-owl.de") and this leads to incomplete HTML being generated by gitweb, along with an error message:

index.cgi: Wide character in subroutine entry at /usr/share/gitweb/index.cgi line 2208.

This patch may fix it, but I'm NOT a Perl guy:

Comments?
