Pause-Jove is for an operating system with process-control, like BSD.  In 
'suspend-jove' it's like hitting ^Z in most other programs under unix.
DOS doesn't have this, so they do the next best thing...

This is actually a simple bug in Jove.  In the 'scrimage' structure in 
'disp.h', the member s_id should be of type 'daddr' rather than 'int'.
On the PC, an 'int' is only 16 bits, where 'daddr' is a long.  The problem
is that when this value is 65536, the line will not be displayed, but it's
really there. (If s_id == 0, line is not displayed...).  When you yank/pop
the line, it gets a new s_id value, which will not be zero anymore.

I am attempting to collect known bugs in Jove 4.14 so a newer version can
be released.
