New Revision: 1936844

Log:
Improve phone number obfuscation rule

* use bounded repetition counts

* require valid area code (must not start with 0 or 1, must not end with 11)

this matches only on US phone numbers, what about this regexp instead ?
/(?!(?:(?:\+|00)\d{1,3})?[^a-zA-Z0-9]{0,3}\d{2,7}(?:[^a-zA-Z0-9]{1,30}\d{2,7}){1,3}\b)(?<![a-zA-Z0-9])(?:(?:\+|00)[\dOIl]{1,3})?[^a-zA-Z0-9]{0,3}[\dOIl]{2,7}(?<![Il1]{2})(?:[^a-zA-Z0-9]{1,30}[\dOIl]{2,7}){1,3}\b/
