I think the best thing to do is to just ignore the issue of whether
the found executable is a directory while testing -x or -f, and test
for -d later on, notifying the user and possibly aborting.  This
second test might have false positives on Cygwin if x/ and x.exe
exist, but I really don't care.  I'd rather warn the user that
something bad is about to happen.

As a data point to support this choice, directories aren't generally
skipped when searching the PATH.  So why should we?
