Standardize fuzzy matching and use fullmatch

Solves two problems:

1. How match fuzziness was used was very inconsistent; make them all the
same, i.e. "if is_fuzzy and limit, apply .* to both sides".

2. Use re.fullmatch instead of re.match to ensure exact matching of the
regex to the value. Without fuzziness, this would sometimes cause
inconsistent behavior, for instance if a limit was non-fuzzy "vm",
expecting to match the actual "vm", but also matching "vm1" too.
