This problem should be fixed in info.el, not in the Texinfo sources.
(It should have been mentioned in the log message as well, btw.)
There's nothing wrong with "see @ref" from the Texinfo usage POV.
Moreover, some old enough versions of makeinfo don't produce correct
output from @pxref that is not the first and the only one in
parentheses, or is not in parentheses at all.

I don't object to the change in the sources, either (which is why I
did merge the change to master), but the change wasn't trivial and
could have had unintended consequences where I didn't see any real
problem to fix in the first place.
