OK, then the doc should mention this, or at least say that the
string might not take the form "HOST:DPY.SCREEN" on some platforms,
and preferably say something about what to expect on the
exceptional platforms (and perhaps give some idea of what use the
exceptional value is - what it can be used for, or what info it
conveys).

I see. Is that then correct, or should the `...' be absent?
There are strings in the manual that are not surrounded by `...'.

Then please say that. E.g., say that the value is useful only for
X Window, or only relevant for it. If the function itself has no
use beyond X Window, then please make that clear.
