 Hello,

 It seems to me that getDirectoryContents should return the contents of
 the current directory
 when passed an empty string, like so:

 getDirectoryContents :: FilePath -> IO [FilePath]
 getDirectoryContents ""   = getCurrentDirectory >>= getDirectoryContents
 getDirectoryContents path = do
 -- ...etc.

 ...this would enable the function to work more easily with the
 functions in System.FilePath
 for example:

 getDirectoryContents (dropFileName "directory/file") == OK
 getDirectoryContents (dropFileName "file") == FAIL

 getDirectoryContents (dropFileName "./") == OK
 getDirectoryContents (dropFileName ".") == FAIL

 ...it also seems like the expected functionality, mirroring the 'ls'
 command on *nix, etc.

 Are there any cases/OSes where trying to open a file named "" wouldn't
 fail? Any other reasons why this is a bad idea?


 Thanks,
 Brandon
