In the yi source code, in HConf.Utils, there's a function that does part
of what you want, but maybe incorrectly (because I wrote it, and it
traverses the string in a rather primtive way).

-- | Break up a string the way a shell breaks up a command into arguments.
-- Similar to 'words', but respects quotes and escaped spaces.  TODO: Verify
-- this function.

shellWords :: String -> [String]
