Reverse LOCAL and REMOTE when invoking P4Merge as a mergetool, so that
the incoming branch is now in the left-hand, blue triangle pane, and the
current branch is in the right-hand, green circle pane.
This change makes use of P4Merge consistent with its built-in help, its
reference documentation, and Perforce itself. But most importantly, it
makes merge results clearer. P4Merge is not totally symmetrical between
left and right; despite changing a few text labels from "theirs/ours" to
"left/right" when invoked manually, it still retains its original
Perforce "theirs/ours" viewpoint.
Most obviously, in the result pane P4Merge shows changes that are common
to both branches in green. This is on the basis of the current branch
being green, as it is when invoked from Perforce; it means that lines in
the result are blue if and only if they are being changed by the merge,
making the resulting diff clearer. Whereas if you use blue as the
current branch, then there is no single colour highlighting changes -
a green line in the result could be a change, but it could also be
something already in the current branch that isn't changed by the merge.
There is no need to swap LOCAL/REMOTE order for difftool; P4Merge is
symmetrical in this case, and a 0- or 1-revision difftool invocation
already gives the working tree ("ours") on the right in green, matching
Perforce's equivalent "Diff Against Have Revision". And you couldn't
swap it anyway, as it would make 2-revision difftool invocation
back-to-front.
Note that P4Merge now shows "ours" on the right for both diff and merge,
unlike other diff/mergetools, which always have REMOTE on the right.
But observe that REMOTE is the working tree (ie "ours") for a diff,
while it's another branch (ie "theirs") for a merge.
