`org-number-to-letters' does expect the number to be greater than
zero.  If it is zero (like in the $0 case) it will return the empty
string.

This can be simply fixed by not calling `org-number-to-letters' if the
is a single zero.  Or, what seems a cleaner solution, to make up a
representation of $0 in letter-notation.

Hope to have some more time to fix this one, if someone else steps in
I'm fine.
