PROPOSAL: export copyPermissions from System.Directory

[Ian Lynagh]

Hi all,

This proposal is:
    export copyPermissions from System.Directory
    http://hackage.haskell.org/trac/ghc/ticket/3392
    (originally part of http://hackage.haskell.org/trac/ghc/ticket/2610)

The
    copyPermissions :: FilePath -> FilePath -> IO ()
function (currently an internal function) should be exported from
System.Directory.

It is not the same as
    getPermissions s >>= setPermissions d
as the Permissions type this uses is lossy.

Deadline: 8th August (2 weeks). 


Thanks
Ian
