If you have control over and can severely limit the paths you're using,
these work fine, but if you want to deal with general paths, you run into
problems. Consider a//b, a/./b, a/../b, a:b, //a, /./a, /../a, and
combinations thereof.

It may be possible to come up with an r.e. that handles all of those
(although I kind of doubt it), but I find it easiest to split the Unix
path on /, then examine each element one at a time, and push appropriate
elements on a second array, which is then joined to become the Mac path.
