* We don't want to end a word on ':' or '!' if there is a
* better match later on in the string. By "better" I mean
* one that is followed by whitespace. This allows the user
* to have targets like:
* better match later on in the string (greedy matching).
* This allows the user to have targets like:
* fie::fi:fo: fum
* where "fie::fi:fo" is the target. In real life this is used
* for perl5 library man pages where "::" separates an object
* from its class. Ie: "File::Spec::Unix". This behaviour
* is also consistent with other versions of make.
