Previously, a diff of non-ASCII strings would incur
three complete copies of the buffers; this changes
reduces it to one.
Also:
- add diff.Bytes function, to avoid unnecessary conversions.
- remove unused diff.Lines and LineEdits functions from API.
- remove TODO to use []bytes everywhere.
We tried it in CL 439277 and didn't like it.
- Document that the diff is textual, even when given []byte.
