readv.2: Minor fixes (part 2) to Will Manley's patch

Mainly: I generally don't want us to be including URLs to mailing
list discussions in a manual page. Either, the issue in the
discussion is worth writing up in the manual page (so that
the reader doesn't have to look elsewhere), or the details
are less important, in which case it is sufficient to note the
existence of the bug. I think this is an example of the latter.
