But:
$ echo 'a' | sed -ne '/a/q;p'
$
Which is what I was trying to do, and it seems to work. The test suite
still passes, at the very least.

Doesn't work at all in my tests (even with -e instead of -ne, which is
what you really meant I guess.) See by yourself:
$ cat test.txt
alpha
beta
gamma
delta
$ sed -e '/^$/Q' < test.txt
alpha
beta
$ sed -ne '/^$/q;p' < test.txt
alpha
beta
$ set -e '/^$/{d;q}' < test.txt
$
Thanks,
