[PATCH 4/4] gitweb.cgi: Centralize printing of the page path

[Luben Tuikov <ltuikov@yahoo.com>]

[-- Attachment #1: Type: text/plain, Size: 322 bytes --]

Centralize printing of the page path so that
if the entity is a blob, we can set the page path
to be the link to the HEAD revision of the
"raw" blob.
