Re: Can I "prune" directories with walkDirRect?

[cblake]

I put various things that "might be useful" for Unix CLI utilities under 
`cligen/` so client code can just have `cligen` as a leaf/sole dependency. 
Directory tree recursion fits that pattern, and stdlib `walkDir*` never seemed 
quite right to me. There is already `cligen/posixUt.recEntries`, for example.
