We used to treat "Both added differently" as a separate "info"
message, just like the "Auto-merging" message, and let "content
conflict" that is an "error" to happen naturally by doing such a
merge, possibly followed by permission conflict which is another
kind of "error". We coalesced these two into a single message.
And this patch breaks them into separate messages. I am not sure if
that aspect of the change is desirable.
The source of "malformed" message seems suspicious. Isn't the root
cause of $msg being empty that merge-file can (sometimes) cleanly
merge two files using the phoney base in the "both added
differently" codepath?
If you resolve that issue by forcing a "conflicted" failure when we
handle "add/add" conflict, I think the behaviour of the remainder of
the code is better in the original than the updated one.
Perhaps something like this (I am applying these on 'maint')?
