Re: [ jEdit-devel ] CTagsInterface

[Shlomy R. <sre...@gm...>]

Hi,

I've just fixed this in SVN.
BTW, except for bug fixes like this one, I am neglecting the main
trunk version of CtagsInterface, and all new features or enhancements
go only to the branch that I've created on CtagsInterface that works
with the trunk of the project viewer. The branch is named
'ProjectViewerTrunk' or something similar, it's the only branch that
the plugin has.
The main trunk will only get bug fixes that I may want to release
prior to the release of the project viewer.
