rationalize bug

I hate to report a bug in my own handiwork, but I noticed
this morning, while writing a scheme numerics test suite
(numtst.c in the Snd tools directory), that if the error is
1.0, rationalize rounds the wrong way:

guile> (rationalize 0.1 1.0)
1.0
guile> (rationalize -0.9 1.0)
0.0

Rats.  I'll try to look at libguile/numbers.c soon.
