Description

This introduces get_newline_for_type(), a utility function that takes

a LineEndings type value and returns newlines encoded as either ASCII

or the given encoding (with BOM stripped).
This logic was previously contained in DiffXReader, but is generally

useful, so it's being split out. That simplifies the DiffXReader code

as well, making some of the logic a lot more clear.

Testing Done

Unit tests pass on Python 2 and 3.

What's the reason to not just do encoding='ascii' in the args list?

Values get passed down directly into this from DiffXReader and, in a change I just posted, DiffXFileSection. Those values are legally allowed to be None, and should not be hard-coded to ascii (None for a diff means "no encoding is known or guaranteed"). To default this to ascii, the call sites would need to conditionally call this with/without the encoding parameter based on their own encoding value.

Ship it!
