Comment (by thomie):

 Yes, that could be considered a bug. If you could try fixing it, then we
 don't need to add another function. Check call sites of `toArgs` and
 `toCmdArgs` to make sure nothing breaks.

 {{{
 *Main> toArgs "a \"b c\" d"
 Right ["a","b c","d"]

 *Main> toArgs "a\"b c\" d"
 Right ["a\"b","c\"","d"]  -- * should be ["a\"b c\"", "d"] I suppose.
 }}}
