Maybe the right thing to do here is insert something other than an "x"
-- a metafied character, for example, something that can't appear in
normal input.  Unfortunately I'm not able to look at the source at the
moment so I don't know whether the string is already metafied at that
point.  At least pick something less likely to form part of an actual
word.
