Does it really?

After you brought up this "one or more", I re-read the docs your patches
touched, thinking that the author might have meant 'zero or more of A'
with these '<A>...'  notation.

And I realized that they made perfect sense.

In general, you can write:

	<command> ...

and read this as "The <command> can be followed by nothing or something
(zero or more) of unspecified kind".  If <command> takes only one type of
zero or more things, you can _clarify the ellipses_ by prefixing them with
what kind of "stuff" you are talking about:

	<command> <remote>...

and read this as "The <command> can be followed by nothing or something
(zero or more) of <remote>s".

On the other hand, you can also say (note that the ellipses stand on their
own and are not associated with <remote>):

	<command> <remote> ...

and read this as "It takes one <remote> followed by nothing or something
(zero or more) of unspecified kind".
