Joerg Wunsch e843ad34c1 Fix a bogon in pcvt that caused a characterset designation to not take 
effect immediately, but required a following (normally redundant) G0
into GL mapping.  This adds one layer of indirection (thus might make it
slower), but fixes the broken box character drawing in pcvt.

Hellmuth and Bruce are unfortunately too busy too review this right now,
but i wanna have it in 2.2 since it has often been asked in the past.
