[PATCH 4/5] gitweb: Clean up code in git_search_* subroutines

[Jakub Narebski <jnareb@xxxxxxxxx>]

1. Replace sequence of

     $foo .= "bar";
     $foo .= "baz";

   with

     $foo .= "bar" .
             "baz";

2. Use href(-replay=>1, -page=>undef) for first page of a multip-page
   view.

3. Rewrap (rearrange) some lines to reduce their length. Some lines
   still have more than 80 characters, but lines are shorter now.

No functional changes.
