[gedit-list] [ANN] Advanced Editing Plugin v0.2

[Marcus Lunzenauer <mlunzena uni-osnabrueck de>]

Hello,

I am pleased to announce that the new release of the Advanced Editing
Plugin, 0.2 is available for download.

After getting a patch from Shaddy Zeineddine, I went to make a new
version of the plugin.

The feature list were streamlined to the essential ones:

- Delete to end of line
- Kill line
- Duplicate line
- Reduce whitespace
- Remove whitespace

BTW thanks to Shaddy the "Kill Line" feature now works as expected and
removes the entire line including the break.

Have fun!

Marcus
