executing external 3-way merge command

and the emerged Kdiff3 contains 3 panes side by side in this order:
left  : ancestor (43bba36ee65d343fbaf2adabfdfde90ea1984e16),
middle: b6e90d8306a670f8035a1728f2c1830088822f32,
right : baa3c6ca3f3f3a15f04122a61629648b435d30b5.
I could determine the revisions by contents of each pane.

I thought the middle pane contains the ancestor. Is it right? How 
can I find out which revision belongs to each panes easily?

The left pane ("A") contains the ancestor. My kdiff3 
displays "(Base)" next to the filename for file 
"A" in order to remind me on that.

There's currently no indication to which revisions file versions 
"B" and "C" belong. We might want to improve 
that. However, it is not clear what the most important information 
to display would be: revision_id? date? author? , because the 
available space is limited.

If you want to see how kdiff3 is called, have a look at the 
mergers.kdiff3 function in  [
http://viewmtn.angrygoats.net/branch/head/file/net.venge.monotone/std
_hooks.lua std_hooks.lua]. Using custom lua code in your monotonerc, 
you can override the standard behavior.
