[xmonad] X.P.Shell, filter empty string from PATH

23 Dec 2009

      Hello,

  * X.P.Shell, filter empty string from PATH

  doesDirectoryExist returns True if given an empty string using ghc <=
6.10.4.
  This causes getDirectoryContents to raise an exception and X.P.Shell does
not
  render. This is only an issue if you have an empty string in your PATH.

  Using ghc == 6.12.1, doesDirectoryExist returns False given an empty
string, so
  this should not be an issue in the future.

Thanks!
Tim
