Fixing up the formatting code which is already merged

I just apply google coding guide like space.

Uploading the same code about + handling just apply the Google Coding Guide.
The previous code is "https://android-review.googlesource.com/#/c/122770/"

This code is about + plus number converting logic for international NANP.
