click/lexer: fix Compound::expand_into sanity check #414

Closed pallas closed 5 years ago

The check here appears to be intended to make sure that we only connect if both indexes are valid; specifically, idx can be -1. Unfortunately, it checks (cp)[0] twice. Instead, check (cp)[1] too.

Thanks, American Fuzzy Lop
