That smells like a convoluted logic but I think I can buy the
argument. If "--conflict=diff3" implies "--conflict=diff3 --merge",
then "--conflict=diff3 --no-merge" should imply "--conflict=diff3
--merge --no-merge" and the latter two cancels out with the
last-one-wins rule, leaving only "--conflict=diff3" that does not
imply anything about "--merge". The conflict style specification
does not have any effect when we are not recreating any merge, so
all of them are ignored in the end. So, it probably makes sense,
even though I find it highly confusing.
Is it likely that "--conflict=diff3 --no-merge" signals that the
user is confused and it is safer to abort the operation before doing
further harm, though, I wonder?
Thanks.
