Is the source for job control available?   Could someone post it either
to me or to {mod,net}.sources?  (Obviously I'm not asking
for the source of the System V shell itself, just the changes for
4.2bsd + job control).  Is this possible to do without violating
ATT contracts, USA export controls, the bounds of good taste, etc.?

(I tried to contact Doug by mail, but the ARPAnet security wouldn't have
any of that.  Now I just hope our news link works at last ...)
