Sigh, yeah there are indeed dragons in this one.
(I would love to know how to fix this in a
portable manner...)

I suppose the real solution is probably to eschew
use of stdio in CVS, but that is rather more work
than I am prepared to attempt at present myself.

Here is a test case for you to use on any version
of cvs you wish (assuming that the one added to
sanity.sh is not sufficient.)
