I forgot to answer this part. By example, I mean an actual grep command
line and sample input that demonstrates the problem, the smaller the
better:
% echo elisp lisp | grep -w lisp && echo good || echo bad
elisp lisp
good
% echo elisp lisp | grep -wq lisp && echo good || echo bad
bad
No idea what causes it, but a quick grep (hah!) for qflag turns up the
following horror:
/* Find out the correct return value according to the
results and the command line option. */
exit(c ? (notfound ? (qflag ? 0 : 2) : 0) : (notfound ? 2 : 1));
which shows that -q *does* affect the exit code, but my brain refuses to
try to understand that code.
