As previously stated, this will still break if the directory containing
foo.exe also has a subdir named foo. But I guess this is not that likely
and is better than the current test.
Using 'test -x && test -f' would be even safer (probably), but would
negate the use of -x on systems like DJGPP and Cygwin that emulate the
executable bit for extension-based executables.
