[PATCH 4/4] gitweb: Fix broken blob action parameters on blob/commitdiff pages

[jk@blackdown.de (Jürgen Kreileder)]

Fix broken blob action parameters on blobdiff and commitdiff pages by
explicitly passing variables instead of relying on global ones.

(The broken parameters on blob links lead to blob pages which show the
blob but with a hash instead of a commit message and have broken
blob_plain (404 - Cannot find file) and tree links (404 - Reading tree
failed))
