I suggest that you disregard that hypothetical lossage.

That was my conclusion, yes.

Yes, you can.  The files with conflicts has the same merge-conflict
markers that you are used to.  When you edit a file with
merge-conflict markers, the development version (Emacs 25.0.50) should
automatically enter the smerge-mode, which is a minor mode with
support for that (see its documentation for a few useful commands).
Furthermore, for each file you save after fixing all the conflicts, VC
should automatically invoke Git with the "git add" command, so that
the de-conflicted file being saved is ready to be committed.

Once you fix all the conflicts, invoke "git commit" to complete the
merge (which "git pull" normally does automatically, but didn't do due
to the conflicts).  After that, you should "git push" to update the
repository on Savannah with your local commits.

I think this is very similar to what you used to do with CVS and bzr,
the only difference is that a singe commit command after fixing the
conflicts is replaced with 2 separate commands: first commit locally,
then push upstream.
