gitweb: Remove git_to_hash function
Remove git_to_hash function, which was to translate symbolic reference to hash, and it's use in git_blobdiff. We don't try so hard to guess filename if it was not provided. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
