[PATCH 4/5] gitweb: Highlight matched part of project description when searching projects

[Jakub Narebski <jnareb@gmail.com>]

Use esc_html_match_hl() from previous commit to mark match in the
_whole_ description when searching projects.

Currently, with this commit, when searching projects there is always
shown full description of a project, and not a shortened one (like for
ordinary projects list view), even if the match is on project name and
not project description.

Showing full description when there is match on it is useful to avoid
situation where match is in shortened, invisible part... well, perhaps
that could be solved (showing shortened description), but it would
require some extra code.

The part about showing match using shortened description no longer
applies after the following patch... though it is an RFC for now.
