sed: Fix parsing bug in find_delim
's/[[x=]//' was parsed as 's/[[=x]//' which (correctly)
raises an error because the "second delimiter is missing", here =].
The two got mixed up because the parser didn't return to
the "inside bracket"-state after encountering an opening bracket
while inside the bracket expression.
