Hmmz, showing a 'best try' would be appreciated. However, I normally can't
resist a good regex, so here it goes:
'/^([1-9][0-9]?)?[0-9](-([1-9][0-9]?)?[0-9])*$/'
Untested BTW. I've made 78-034-89 invalid, as a number should not start
with zero, unless it's only 1 zero. 't Would be simpler if it was valid,
your choice.
