commit 76dec7bbd4e8761249a339db5f13f7e63a37aac3 (HEAD -> master)
Author: Michael Kerrisk [off-list ref]

    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.
