Description
=begin
It seems regular expressions with negative lookbehind do not treat case properly if
- there is an alternative in the lookbehind
- one alternative is longer than one char
I believe lines 18 - 20 are wrong and should return the same result as line 17.
Interestingly if the alternatives in lookbehind are exchanged the expression works as expected (lines 23 - 25).
