Ok.  I'm not sure either.  I know that Solaris has an intro(1)
manual page which describes general command behaviour, standard
option parsing, etc.  I guess that might be a suitable place, but
cygwin has no such manual page.

That turned out to be an incorrect assumption on my part.  I have
worked with many UNIX flavours, and assumed that I had been using
this syntax on all of them, but it turned out to be that I had
only used it on Solaris where this syntax actually works.

I'm not sure where it really ought to be documented.  :-/
