Indeed, it depends on the mergetool, but personally I use vimdiff3
(which I authored). All I need are diff3 conflict markers plus some
colors.

Yes, and I found it curious that all this sprang up from my suggestion
to get out of our comfort zones.

Since I don't have my beloved `g mt` alias, I've been forced to do
`g mergetool --tool=gvimdiff3`, once there, I decided to use gvimdiff2 a
couple of times, and I even gave meld a try.

Now, I didn't dare to remove merge.conflictstyle from my config, but if
I did, I would I have immediately noticed that:

  git merge --<tab>

There's nothing to easily switch conflict styles.

Seems like there's many areas of opportunity.

Cheers.
