On a closer look, I see three different places in the
functions-matching.html page that talk about doubling backslashes, of
which this one might be the least bogus, since it at least provides
a cross-reference to someplace where you would read about
standard_conforming_strings.

I suggest replacing the first and third cases with something along the
lines of

Note: if you have standard_conforming_strings turned off, any
backslashes you write in literal string constants will need to be
doubled. See Section 4.1.2.1 for more information.

The second case is just a parenthetical comment and perhaps could be
removed.
