Whoops.
I forgot a minor detail :-)
Your report exposed a bug in mv.c:
mv (coreutils-4.5.3) mistakenly strips trailing slashes
from the SOURCE name in some cases. Here's a fix:

Maybe now, my preceding message makes more sense,
since with the modified mv, your example evokes this diagnostic:
$ ./mv b/ c
./mv: cannot move `b/' to `c/b': Not a directory
[Exit 1]
Thanks again,
