It lets quote_c_style_counted() do its escaping and then (1) if the input string got escaped, which is checked by seeing if the result begins with a double-quote, declare that we are done. If there wasn't any SP in the input, that is OK, and if there was, the result is quoted already so it is OK, too. (2) if the input string did not get escaped, and the result has SP in it, enclose the whole thing in a dq-pair ourselves. Instead we can scan the path upfront to see if the input has SP in it. If so, we tell quote_c_style_counted() not to enclose its output in a dq-pair, and we add a dq-pair ourselves. Whether the input had bytes that quote_c_style_counted() uses backslash quoting, this would give us a desired quoted string. If the input does not have SP in it, we just let quote_c_style_counted() do its thing as usual, which would enclose the result in a dq-pair only when needed.

Similarly, sq_must_quote() is fed each byte from the string being C-quoted. No behaviour change intended.
