[PATCH] gitweb: Fix setting $/ in parse_commit()

[PATCH] gitweb: Fix setting $/ in parse_commit()

[Petr Baudis]

If the commit couldn't have been read, $/ wasn't restored to \n properly,
causing random havoc like git_get_ref_list() returning the ref names with
trailing \n.

Aside of potential confusion in the body of git_search(), no other $/
surprises are hopefully hidden in the code.
