There is a bug in the implementation of 'sed' on Microport System V/386
that causes checkgroups to incorrectly report moderated groups as being
unmoderated. This bug also cropped up in rn's newsgroups functions (the
'l' command at the top level prompt). This has been reported to uPort
and has been passed on to their bug people. I'm including a copy of my
original bug report for anyone who might be interested in hacking a kludge
up. My "fix" is to ignore the (un)moderated messages.
I would be interested in hearing if any other 386 Unix implementations
display this problem. The bug report follows.

BUG>Problem:
BUG>
BUG>According to the documentation, sed(1), when performing a subsititution,
BUG>may have the flag "p", as in s/regular expression/replacement/flags, eg.
BUG>s/foo/bar/p --- substitute bar for foo and print if a replacement was
BUG>made.
BUG>
BUG>This is not working correctly. Example:
BUG>
BUG>input file:
BUG>abc
BUG>def
BUG>abe
BUG>aaa
BUG>
BUG>command script file:
BUG>/a/s/a/x/p
BUG>d
BUG>
BUG>save as infile and sfile; execute the command "sed <infile -f sfile".
BUG>It should print:
BUG>xbc
BUG>xbe
BUG>xaa
BUG>
BUG>It does not. It prints nothing. Remove the 'd' from sfile and it
BUG>properly echos the input put does not print the pattern space.
