While I like the fact that somebody is trying to tackle the
consistency issue, I do not like the approach itself. Fudging
the issue at the merge-tool UI level may make things appear more
consistent when viewing the merge from within merge-tool, but it
makes the views merge-tool gives and vi/less gives inconsistent.
It would be a lot more sensible to make sure that we always show
the side that the end-user modified first and then the side the
other party changed.
A regular merge, cherry-pick and revert all start from user's
side and play the change from the other side, and conflicted
hunks are shown in the right order. It is only "rebase" (with
or without -m) that gets it wrong. Even though it internally
operates as if our own changes are coming from the other side,
we should show our change first and then theirs to make it
consistent and easier to read.
So how about doing it like this, instead? I am not proud of the
use of an environment variable to pass this control around, but
the idea should be obvious.
Note that some tests are written to expect the current hunk
order and will start failing, so if we were to go this route, we
would need to adjust them as well.
