In the current git version of zsh (zsh-5.2-97-g1aec003), this bug is now
fixed for literal patterns:
case b in
( ['a-c'] ) echo 'false match' ;;
( [a-c] ) echo 'correct match' ;;
esac
outputs "correct match" as expected.
However, for variables there is now a new problem, the opposite of the
old one: unlike in every other shell, a range is not recognised even if
the variable is *not* quoted. So quoting a variable still has no effect,
it's just that range parsing from variables was disabled altogether. The
following code:
myrange='a-z'
somevar='c'
case $somevar in
( *[$myrange]* ) echo "$somevar is part of $myrange" ;;
esac
outputs "c is part of a-z" on every shell except current zsh.
Quoting the variable ( *["$myrange"]* ) should make it output nothing.
Thanks,
