This patch makes getpgrp() conform to POSIX. I have some qualms about
it because getpgrp() will now return 0 in cases where it would
previously return -1. I don't know if this is likely to break any
applications.
The patch fixes the problem reported here:
https://cygwin.com/ml/cygwin/2019-07/msg00166.html.
See especially the comments in
https://cygwin.com/ml/cygwin/2019-07/msg00208.html
about bash. Although my patch does fix the specific problem I
reported about debugging bash, I'm not sure what other side-effects it
might have.
