For me it's friendly enough. One key-press in Emacs and I get:
--- upper/xx.txt
+++ lower/xx.txt
@@ -1,7 +1,7 @@
-B
+b
C
D
E
F
-I
+i
In a separate window, that is roughly what you've get in the "merge"
output in the first place, but even more compact.
My point is that once Git provides enough context, a good interactive
tool will do the rest just fine, beneficial to the end-user.
