\c matches the escape sequence or literal character c
for strings and REs:
\c any other character 'c' literally, e.g., \" for " and \\ for \
(also shown on p. 31-32 and discussed in some detail on p. 28-29)
The implication is of course that all 'x' are valid in '\x' and thus
no warning should ever be given. (except inside a character class in
an RE where only '\', '^' at the beginning, and '-' between two
characters have any special meaning)
