The username search in Special:Listusers does not translate underscores into
spaces, unlike nearly all the rest of MediaWiki. One consequence of this is
that [{{fullurl:Special:Listusers|username={{PAGENAMEE}}| Listusers entry for
the User who's page this is on] fails for users with spaces in their username.
This ought to be trival to fix, I hope.
