Re: [PATCH] gitweb: fix link to parent diff with pathinfo

> Gitweb, when used with PATH_INFO, shows a link to parent diff
> like http://somedomain/somerepo.git/commitdiff/somehash?hp=parenthash.
> That link reports "400 - Invalid hash parameter".
>
> As I understand it, it should instead directly point to the parent diff,
> i.e. turn it into http://somedomain/somerepo.git/commitdiff/parenthash,
> and delete 'hash_parent' element from the %params hash once we used it,
> otherwise the '?hp=parenthash' string is appended.
