Yup, I often find myself comparing the base part (lines between |||
and ===) with our part (lines between <<< and |||) and their part
(lines between === and >>>) while looking at the diff3 output to see
what unique change each side did, in order to come up with a
conflict resolution.
I do this often enough to wonder if I should write a small "filter"
that I can pipe a whole "diff3" <<< ... ||| ... === ... >>> region
to and convert it into to diffs, but not often enough to motivate
me to actually write one ;-).
