[terminology] Handling csi escape code 'Z'. 

Unfortunately it doesn't fix the 'rendering' problems of the
application it came from yet (mutt-kz), but it seems to be what
http://www.inwap.com/pdp10/ansicode.txt says it should do.

Anyone using mutt with a sidebar (only on sidebar showing mode we get
the booboos, but not on other terminals) willing to help? :P
