[PATCHv6 0/5] gitweb: PATH_INFO enhancement

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Sixth attempt for my gitweb PATH_INFO patchset, whose purpose is to
reduce the use of CGI parameters by embedding as many parameters as
possible in the URL path itself, provided the pathinfo feature is
enabled.

The new typical gitweb URL is therefore in the form

$project/$action/$parent:$file..$hash:$file

(with useless parts stripped). Backwards compatibility for old-style
$project/$hash[:$file] URLs is kept, as long as $hash is not a refname
whose name happens to match a git action.

The main implementation is provided by paired patches (#1#2, #4#5)
that implement parsing and generation of the new style URLs.

Patch #3 is a minor improvement to the URL syntax that allows web
sites to be properly browsable in raw mode.

The patchset depends on my previous input parameter handling patch
currently waiting in 'next'. This resend fixes a couple of problems
I found in v5.

Giuseppe Bilotta (5):
  gitweb: parse project/action/hash_base:filename PATH_INFO
  gitweb: generate project/action/hash URLs
  gitweb: use_pathinfo filenames start with /
  gitweb: parse parent..current syntax from PATH_INFO
  gitweb: generate parent..current URLs
