[Mediawiki-l] Search fix: secondary search

[John Andrews]

The help for search says this regarding secondary search:

	Oddly, sometimes no context is shown.

We (Christian Zankel) seem to have fixed this by applying the
following diff to mediawiki-1.3.8/includes/SearchEngine.php:

402a403
 >                       --$contextlines;
408d408
<                       --$contextlines;

Resulting in code that looks like this:

                 foreach ( $lines as $line ) {
                         if ( 0 == $contextlines ) {
                                 break;
                         }
                         ++$lineno;
                         if ( ! preg_match( $pat1, $line, $m ) ) {
                                 continue;
                         }

                         --$contextlines; # <<<<==== Moved past continue.
                         $pre = $wgLang->truncate( $m[1], -$contextchars, "..." );
