Surprisingly, groff supports multiple copy mode escapes at the
beginning of an escape sequence: \, \E, \EE, \EEE, and so on all do
the same outside copy mode, so let them do the same in mandoc(1), too.
This fixes an assertion failure triggered by \EE*X that tb@ found
with afl(1). The first E was consumed by roff_expand(), but that
function failed to recognize the escape sequence as the expansion
of a user-defined string and handed it over to mandoc_escape(),
which consumed the second E and then died on an assertion because
it is not prepared to handle user-defined strings. Fix this by
letting *both* functions handle arbitrary numbers of 'E's correctly.
