[PATCH 0/5] Show extra branch refs in gitweb v6

First patch just adds a comment I though would be useful when trying to understand how config parsing is done.

Second patch splits some code to a function.

Third patch fixes validation functions to return either 0 or 1, instead of undef or passed $input.

Fourth patch adds the extra-branch-feature and some documentation.

Fifth patch adds some visual differentation of branches from non-standard ref directories.

Krzesimir Nowak (5):
  gitweb: Add a comment explaining the meaning of $/
  gitweb: Move check-ref-format code into separate function
  gitweb: Return plain booleans in validation methods
  gitweb: Add a feature for adding more branch refs
  gitweb: Denote non-heads, non-remotes branches
