Also trim trailing spaces in to_count/to_int inputs

Browse source 
Previously we would already trim leading spaces in inputs to `to_count`
and `to_int`, effectively by just passing the behavior of the low-level
functions used in their implementations to the user. While this was
useful it was also inconsistent in that we did not allow trailing
spaces which we enable with this patch.
