We actually don't do that, and for this reason:  If it was guaranteed that
\q meant the same as q, it would be impossible to give \q a meaning in
some future version of the language.  Therefore, we say that \q is
undefined, so that it can be treated by an implementation as an error,
as q, or as something new in advance of future standardization.
