These will be expanded later as I come up with good test cases; for now,
these seem to be enough to trigger bugs in base gnugrep and expose missing
features in bsdgrep.
The copyright notice was erroneously introduced as one from the NetBSD
foundation due to it being copied from a file in the NetBSD test suite, but
this file itself is not derived from or supplied with the NetBSD test suite.
MFC after: 3 days
of calling grep -r without it, and saving the output to a file
This ensures that any errors thrown via grep -r are caught, not lost, and uses
existing atf-sh idioms for saving files.
Tested with: bsdgrep, gnu grep (base, ports)
