[PATCHv3 1/5] gitweb: 'pickaxe' and 'grep' features requires 'search' to be enabled

[Jakub Narebski <jnareb@gmail.com>]

Both 'pickaxe' (searching changes) and 'grep' (searching files)
require basic 'search' feature to be enabled to work.  Enabling
e.g. only 'pickaxe' won't work.

Add a comment about this.
