### Notes
The examples show we should not take the specification as a specification;
just a rough guideline. According to the specification, 
" +44 1148820341" fails the criteria not once, but twice: it contains
a leading space (not allowed in the specification), and it has only a
single space between the '+44' part and the rest, where the specification
requires two.

We therefore conclude the examples just contain random spaces, and we
can completly ignore any white space in the input.
