egrep bug

[guy at rlgvax.UUCP]

It's a V7 bug; a "diff" between V7 and 4.1BSD "egrep.y" reveals that this
part of its behavior hasn't changed.  On the other hand, a quick check of
the System III "egrep.y" reveals that it does NOT exit if a file does
not exist; in fact, it does exactly what you wanted it to (i.e., it eventually
exits with an exit code of 2).  So don't feel (too) guilty about changing it.

Any chance UCB will get an academic USG license ($800 for the first CPU, and
I think free for all subsequent ones) any time in the future?  Then they
will be able to send out more new Bell stuff with their releases, and won't
have to reinvent things in order to get around the license.  It'll help
make a "best of all possible worlds" system (after all, believe it or not,
there are some things that USG UNIX does right and Research UNIX - which
4.?BSD is ultimately derived from - doesn't), as well as the other way around -
ever tried reading in a "tar" tape from a foreign site on a system (like USG)
which lets you (for which read "tar") give away files?  Feh!
