I support this new proposal.
To summarise for people who have not been paying full attention:
takeDirectory "Main.hs" = ""
takeDirectory "Main.hs" = "./"
The purpose being that one can always take the directory and get a valid
path to use with a file system function, eg createDirectory.
"./" </> "Main.hs" = "./Main.hs"
It was initially proposed that </> eat "./" on the left hand side but
the current proposal leaves the behaviour of </> unchanged.
