    Fix configure's snprintf test so it exposes HP-UX bug. · 9bed827b
    Tom Lane authored
    Since commit e1d19c90, buildfarm member gharial has been failing with
    symptoms indicating that snprintf sometimes returns -1 for buffer
    overrun, even though it passes the added configure check.  Some
    google research suggests that this happens only in limited cases,
    such as when the overrun happens partway through a %d item.  Adjust
    the configure check to exercise it that way.  Since I'm now feeling
    more paranoid than I was before, also make the test explicitly verify
    that the buffer doesn't get physically overrun.
