One of the things I notice when watching a normal git user face a
merge conflicts is the output is very verbose (especially when there
are multiple conflicts) and it's hard to spot the important parts to
start resolving conflicts unless you know what to look for.
This is the start to hopefully help that a bit. One thing I'm not sure
is what to color because that affects the config keys we use for
this. If we have to color different things, it's best to go
"color.merge.<slot>" but if this is the only place to color, that slot
thing looks over-engineered.
Perhaps another piece to color is the conflicted path? Maybe. But on
the other hand, I don't think we want a chameleon output, just enough
visual cues to go from one conflict to the next...
