many and takeWhile crash in combination

[r-toroxel]

There is no termination, once the compiler starts on
val la = many(takeWhile(c => c != 'r')).parseOnly("awe").

Yeah many doesn't work with parsers that can successfully consume zero characters; you can parse an infinite number of empty strings. I'm not sure how to fix this without distinguishing between empty and non-empty parsers at the type level.
