I do not think there is much we can do at this point in time (but
notice that I did say "much", and didn't say "anything").

The way we replay any potentially conflicting change and present the
result to the end user in Git is uniformly to add the cleanly
applied parts to the index while leaving the conflicted ones as
unmerged index entries, but "git stash apply/pop" does not follow
this pattern.  I think this is partly because the command is also
used to "stash away" a work-in-progress changes to the index, and
avoiding to touch the index with the changes in the working tree
would more closely match the behaviour of the command when there is
no conflict.

I notice that I said the same thing long time ago, i.e. in the
initial round of review:

In the above, I suggested to "git reset" when there is no conflict.
I think this line of thinking can be followed even further to
selectively reset the paths that were cleanly merged (which is added
by the call to merge-recursive), leaving _only_ the conflicted paths.

Would that give us a better outcome?  I dunno.
