[PATCH 0/1] Don't allow getpgrp() to fail

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.
