I think this is a docstring mistake. IIUC, the equation
(split-string-and-unquote (combine-and-quote-strings strs)) == strs
only holds if STRS is a list containing a single string. The point the
docstrings are trying to make is that combine-and-quote-strings performs
string quoting, while split-string-and-unquote performs unquoting.
If there are no objections to this interpretation, I'll check in a doc
fix shortly.
