I don't think so, I think it's a weakness in ainsl. And the \[ \] probably
doesn't work either because the shell will strip off the \, you'll need
something like \\[ or even \\\[.

Thomas, shouldn't ainsl not escape anything while matching and instead use \Q
and \E in the match operation to disable regexp specials? Of course, it should
take care of ^ and $ and change that to ^\Q$line\E$.

Best,
Michael
