In copy mode one can copy to a screen-exch file using space and then '>'
to end selection. The screen background part crashes after entering '>'.
Copying to internal buffer (ending selection with space) works corectly.
It seems to concern all 3.9.x version in RH 6.1, 6.2b and RawHide, e.g.
the most recent 3.9.5-3. 3.7.6-9 from RH 6.0 works correctly so may be
used instead (hoping it is not less secure then 3.9, don't know). Tested
on i386 and sparc.
Solved in beta 3.9.6c by the author. Simplistic patch also available from me
Got the patch from rzm, it works.
