This is specifically what I was trying to avoid.  The current behavior is
now encoded in the DNA of the cygwin community.  If we change things so
that -rsv doesn't do the "right" thing anymore, we'll be foreever asking
people to do '-scnver'.

I realize that 'cygcheck -c' is not precisely equivalent to 'rpm -q' but
'cygcheck -c' was never intended to be an exact replacement for 'rpm -q'.
If the only concern is that cygcheck takes a long time, now, then, like
I said, that is something that can be rectified.
