[Talk-ca] Preferred phone number format

[Matthew Darwin]

 From the wiki, I am proposing this format specifically:

(phone=+<country code>-<area code>-<local number>, following the RFC 
3966/NANP <http://en.wikipedia.org/wiki/NANP> pattern)

However, convert that to "contact:phone=" instead.

The reason I like the one with hypens (vs spaces) is that when you add 
additional comments in the field as in "+1-800-555-1234 (toll-free)" 
or use the letters instead of numbers "+1-555-GOT-BEER" the hypens 
make it much more clear what is part of the phone number and what is not.

That is a goal to shoot for, as what it calls "user agents" is what I referred to as "a phone number parser."  There is some caution ("not voted on just documentation of use") about country-specific usage, should Canada fully embrace something unique.

That could be a short Overpass Turbo script plus a few minutes of human analysis similar to the sort you (Matthew) are doing now.
