I don't like either of these (maxheight=none/unsigned/default/unspecified),
because we should map what we see. If there is no sign, there is nothing to
map. Applications can make their assumptions on their own.

Please remove the nonsensical and nonstandard maxheight=unsigned from the
german wiki instead of polluting other pages with it.
