Comment (by leroux):
I've implemented findFiles, findFilesWith, and findExecutables as
convenience functions.
`findFilesWith` checks for existence and applies another boolean functions
for filtering purposes (such as checking permission bits).
`findFiles` and `findExecutables` are special cases of `findFilesWith`.
`findFile` and `findExecutable` are now simply `listToMaybe` of
`findFiles` and `findExecutables` respectively.
I also took thoughtpolice's views on what a correct implementation is
(fyi).
