Log:
Audit all .scm files for cases where null objects were assumed to be #f.

In most of these cases, I know the value is always returned from C, so we
can use "null?".  In cases where I wasn't sure, I make it check for either
#f or null?.  Hopefully, I got 'em all.  But, really, what are the chances?
