Bug#436436: "Max. results" is ignored when searching the "Application Manuals"

["Yair K" <cesium2@gmail.com>]

Package: khelpcenter
Version: 4:3.5.7-2
Tags: patch

When the "Application Manuals" box is checked, and "Max. results" is set  
to a value other than 10, a search in khelpcenter will still return only  
10 matches (instead of the value from "Max. results") from the manuals  
even if more matches are available. On the other hand, searching "UNIX  
manual pages" does listen to the "Max. results" value. The reason is that  
khelpcenter uses htdig to search the manuals, and the $maxnum variable  
(i.e. what "Max. results" is set to) is never passed to htdig in  
khc_htsearch.pl . htdig's default is to provide only 10 results. The  
attached patch fixes khelpcenter on my system. (It also removes an  
occasional false result from the search: "[index.html]").
