| '$("$1" $prev help 2>&1 </dev/null | sed -ne "/^[[:space:]]/p")' \ |
I also suggest quoting the regex passed to sed. I noticed that sed -ne /^[[:space:]]/p produces an error message and outputs the help text of sed in my Debian 10. This is caused by nullglob: the word /^[[:space:]]/p contains a glob pattern [[:space:]] matching nothing, so sed receives just an option -ne as its commandline arguments.

I'm sorry. This workaround turned out to fail to produce the candidates. I expected that help should output candidates even without stdin, but it seems to fail when stdin is redirected /dev/null. I'll think about an alternative workaround.

Closes #753
It's unfortunate that the help output goes to stderr, but I suppose this is good enough.
