False positive in rosetta stone pattern matching

[TannerRogalsky]

Hey Paul! I found a small bug in the pattern translation code. I think that the first ROSETTA_STONE entry is matching hyphens when it shouldn't be and turning a pattern like ^(%d+)-(%d+)$ into ^(\d+)*?(\d+)$.

moonshine/vm/src/lib.js

Line 42 in adff2ed

'([^a-zA-Z0-9%(])-': '$1*?',

Cheers, Tanner. The regex translation is a tricky part of the VM. I'll take a look.

Haha, as regexes can sometimes be.
