(split-string-and-unquote (combine-and-quote-strings STRINGS)) fails on

Subject: (split-string-and-unquote (combine-and-quote-strings STRINGS)) fails on trivial case

The documentation strings for both split-string-and-unquote and
combine-and-quote-strings state that they attempt to achieve this

  (split-string-and-unquote (combine-and-quote-strings strs)) == strs

Here is a trivial case that they fail on; the following sexp wrongly
evaluates to nil:

  (let ((l '("a b" "c")))
    (equal l
           (split-string-and-unquote (combine-and-quote-strings l))))

I hope this problem report is helpful.
