Straighten up how exceptions are detected in the 'wanted' callback

[vpit]

Hello,

The detection of the directories that must be skipped when collecting perl files was pretty lax. In particular, it abused regexps of the form m![^\\/]?inc!, probably with the goal of allowing both "inc" and "/inc". Unfortunately, m![^\\/]?inc! can match a lot of other things, such as "vincent", which happens to appear in my TEMP environment variable, and which ultimately made the test suite fail.

I've rewritten this whole section to use File::Spec->splitdir to split the directory name in chunks, and then decide on whether the directory should be skipped depending on their value. The result should be more deterministic.

The m!Build$! regexp that appears next line should probably be anchored as well, but I'll leave that to your appreciation.

I'd advise you to roll an alpha release out first before making it official, since this change touches a core path of the module.

Vincent

thank you! I started with your patch and expanded on it, and added a test. This will be in release 2.001. sorry it took so long!
