Agreed on the higher value of handling 3-part conflicts.

" Currently, the names are

I'm not sure the name 'upper' adds anything if it's displayed in the upper
pane, which suggests to me that 'a' is no worse. (And if 'upper' is displayed
anywhere else, it's causing confusion.

Glenn, Kaushal,

"A" and "B" are the names diff3 uses for the conflict markers.
"A" and "B" are the names used in the documentation.

"UPPER" and "LOWER" are useless since they don't match up with anything else (the conflict markers and the documentation).
"UPPER" and "LOWER" are confusing since they are often shown on the left and right respectively.

Why is this change good? What am I missing?
