[BUGFIX PATCH 1/4] git-instaweb: Fix issue with static files for 'plackup' server

[Jakub Narebski <jnareb@gmail.com>]

The default (in gitweb/Makefile) is to use relative paths for gitweb
static files, e.g. "static/gitweb.css" for GITWEB_CSS.  But the
configuration for Plack::Middleware::Static in plackup_conf assumed
that static files must be absolute paths starting with "/gitweb/"
prefix which had to be stripped, e.g. "/gitweb/static/gitweb.css".
This in turn caused web server run by "git instaweb --httpd=plackup"
to not access static files (e.g. CSS) correctly.

This is a minimal fixup, making 'plackup' web server in git-instaweb
work with default gitweb build configuration.

The regexp is probably too strict: qr{^/static/} should be enough,
but I didn't want to change too much at once.

This bug was not noticed because we don't have any test for
git-instaweb, not mentioning tests for all web servers supported.  And
the fact that I was checking "git instaweb -httpd=plackup" against
gitweb.cgi built with custom configuration (including the fact that
GITWEB_CSS="/gitweb/static/gitweb.css").

tadzik, does that fix the issue you noticed?

Junio, could you apply this before 1.7.4?  Thanks in advance.
