/*
 * Select_HyperSearch_Matches.bsh - A Beanshell macro script

 * HyperSearch in the current EditPane. J.Holy: It selects exactly from the 
 * beginning of the match to its end thus possibly spanning across multiple
 * lines.

 * Notes on use:
 *
 * This macro is based on 'Write_HyperSearch_Results.bsh', so has similar
 * limitations.  It uses the last HyperSearchs generated, so it is best run
 * directly after executing a search.
 *
 * Simply Adapted for jEdit 4.1 API by Saturn
 *
 * Modified by Jakub Holy, Oct 6, 2004 AD, to select exactly the whole match.
