 <!-- TODO(crbug.com/603217): Use i18n instead of string literals. Figure out
                              what i18n to use for keypad, ie, does 1 ABC make
                              sense in every scenario? -->

Are these format changes created from tooling?

[sammiequon, 2017/04/27 19:26:44]

The html ones are manual. The style guide says 4 space indent for line wrapping.
