Accomodate for groff's crappy behaviour wherein an unrecognised
single-character escape (and ONLY this type of escape) will map back
into itself:
"If a backslash is followed by a character that does not
constitute a defined escape sequence the backslash is silently
ignored and the character maps to itself."
(From groff.7.)
