[PATCH 7/8 v6] gitweb: Add optional extra parameter to die_error, for extended explanation

[Jakub Narebski <jnareb@gmail.com>]

From: John 'Warthog9' Hawley <warthog9@kernel.org>

This is a small change that just adds a 3rd, optional, parameter to die_error
that allows for extended error information to be output along with what the
error was.

Changes from version from 'Gitweb caching v5' and
  git://git.kernel.org/pub/scm/git/warthog9/gitweb.git gitweb-ml-v5

* Slightly changed commit summary (commit description).
* Align with spaces, instead of indenting with tab

Those changes are purely cosmetic; the commit is practically unchanged
from the version by J.H.
