gitweb: do not run "git diff" that is Porcelain
Jakub says that legacy-style URI to view two blob differences are never generated since 1.4.3. This codepath runs "git diff" Porcelain from the gitweb, which is a no-no. It can trigger diff.external command that is specified in the configuration file of the repository being viewed. This patch applies to v1.5.4 and later.
