I think it's fine. The FOR is a noise word that's useful only to
make the command's grammar vaguely resemble English. For precedent,
consider INSERT, which must have INTO but that's not part of the
command tag.

If anything, I'd change the manual. "WAIT FOR" is neither short
nor a useful description of what's being waited for. Either "WAIT"
or "WAIT FOR LSN" would be more plausible as a page heading.
