It is a typo. Thanks.

I've noticed the use of ~! in trip.rc in a few places:
if (~! `` '' {echo --} $nl)
fail echo --
I don't understand what this is supposed to do.
According to the grammar, TWIDDLE should be followed by an optional
caret and words. I don't see anything in the grammer allowing ~ to be
followed by a BANG (unless the ! is a word, in which case there should
be white space after the TWIDDLE, no?).
Is the sense of this backwards? Should it be '! ~' (or !~) ?
Thanks,
Hamish.
