[PATCHv5/RFC 0/6] Moving gitweb documentation to manpages

The original patch adding manpage for /etc/gitweb.conf was sent by Drew Northup (as can be seen from shortlog); I have added manpage for gitweb itself, inspired by his patch. Unfortunately Drew doesn't currently have time to work on this patch (patch series), so that is why it is me resending this series (again).

Compared to previous version

  "[PATCH/RFCv4 0/4] Moving gitweb documentation to manpages"
  http://thread.gmane.org/gmane.comp.version-control.git/181605

it has much improved gitweb.conf.txt manpage, and "Documentation: Preparation for gitweb manpages" commit message, thanks to feedback provided by Jonathan Nieder.

New in this series are patches 4 and 5, which add links to the newly created gitweb documentation and gitweb config variables from other manpages, respectively.

Note that only "Documentation: Preparation for gitweb manpages" (which is not strictly necessary) and "gitweb: Add manpage for gitweb" (which didn't get as much review as "gitweb: Add manpage for gitweb configuration files" are still marked as RFC.

I have checked that RPM generation of 'gitweb' package works correctly wrt. gitweb documentation.
