Shifting status line in some terminals

[notori0us]

In some terminals (particular the Mac one) it seems that every time I invoke sky bison, the status bar shifts up one line.

I don't have access to a mac to reproduce, and thus I can't reproduce at this time. However, we can keep this open until I get the chance to test on a mac.

No worries, here's steps to reproduce in PuTTY as well (not that that is that helpful either ;) )

1. invoke skybison with :
2. type something arbitrary (ie, word)
3. hit escape
4. repeat

This shifts the status bar up one line each time.
