- The regexp for the "check if formula name is used in formula's
description" cop matches every instance of the formula name if it
exists, whether it's in a word or not.
- For example, the formula `mon` has the description "Monitor
hosts/services/whatever and alert about problems". This makes
`brew audit --strict` complain because it matches "Monitor",
which isn't the formula name! The formula `pass` has the description
"Password manager". Again, the strict audit matches "Password",
which isn't an issue.
- Instead, this change matches on a word boundary, so it will match
`mon:`, or `mon `, but not "Monitor", or, for example, "harmony".
- I've changed the tests to account for this change.
