SF.net SVN: geany-plugins:[123] trunk/spellcheck

Revision: 123 http://geany-plugins.svn.sourceforge.net/geany-plugins/?rev=123&view=rev Author: eht16 Date: 2008-07-16 22:32:34 +0000 (Wed, 16 Jul 2008)

Log Message: ----------- Note: Don't use this revision for productive use! Experimental changes in word retrieval to work better with complex Unicode characters like in Hindi. Use Scintilla's messages for finding word start and end positions instead of my own variant which didn't work well in Hindi. Add a temporary option to switch between Geany's word retrieval method when showing the editor menu or use an alternative one (only for testing). This code is still in testing and should be considered as WIP.
