Yes, I guess you need to skip over those before untokenizing.  That matches
this line in spckword():

    if (*t == Tilde || *t == Equals || *t == String)
	t++;

The next block is then skipping other tokens.  I wonder if that
would be the right place to put the surgery?  E.g. if thereʼs
a Dash or anything else we want to be able to treat literally, dupstring
at that point within spckword() and replace those?

However, thatʼs late enough that itʼs past the point where we check the
word isnʼt already found in a hash table --- and presumably we need at
least to have the dashes fixed by that point.  But still not sure we
actually need two separate token-based interventions.
