gitweb: Use @diff_opts, default ('M'), as git-diff and git-diff-tree paramete
Added new global configuration variable @diff_opts, which holds additional options (parameters) to git-diff and git-diff-tree, usually dealing rename/copying detection. Default value is '-M', taken from git_commit subroutine. Description of options and their approximate cost by Junio C Hamano. Changes: * git_commitdiff, git_blobdiff and git_blobdiff_plain now use '-M' instead of '-M', '-C' * git-diff now uses the same options as git-diff-tree * git_comittdiff_plain now uses '-M' instead of '-B' and is now rename-aware * git_rss uses now '-M' instead of () Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
