Not really. I've yet to see a 'program --help' output that contained
backslashes. But oh well, I guess it doesn't matter now.
Not a configure script, but GNU echo does include backslashes, as does
GNU tr.
Uhm, I can do better:
find /sw/bin/* | xargs grep -l -- --help | while read i; do ($i --help
2>&1 | fgrep -q \\) && echo $i; done
