Subject: gitweb: Make search type a popup menu
X-Git-Tag: v1.4.4-rc1~67^2~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=88ad729b73264025d2d4c187ff74432d7cacafb2;p=git.git

gitweb: Make search type a popup menu

This makes the multiple search types actually usable by the user;
if you don't read the gitweb source, you don't even have an idea
that you can write things like that there.
