Fixed redraw issue in vim-konsole

A while ago I’ve written the little vim-konsole plugin which makes Damian Conway’s vim-autoswap working with KDE’s Konsole application.

This caused some redraw issues in Vim when switching buffers, whichs is very annoying. I needed to press C-L to force a redraw everytime this issue occured.

I didn’t know the reason for this issue or what plugin is causing it. But today I investigated the issue and found out that my own plugin was causing the issue. Blame on me, but I’m really not a Vim-Script expert.

However, the problems seems to be fixed now with my latest change. See https://github.com/gergap/vim-konsole/tree/master
