Generate diffs between base and tip commits
Review Request #10130 — Created Aug. 27, 2018 and submitted — Latest diff uploaded
get_diff_filesutility can now generate a list of files to diff
that exist between two commits in a diffset. This allows us to generate
diffs between two commits (and therefore to see the diff of any
individual commit). There is currently no UI support for this behaviour,
but that is comming in a future patch.
Ran unit tests.
