[issue3128] Call file merge util through mercurial.ui.ui

[Kirill Gagarski]

New submission from Kirill Gagarski <gagarin.gtn at gmail.com>:

When I am doing "hg commit" the editor for commit message is called through
mercurial.ui.ui.edit() method. It's good because if i want to change
behaviour of editor i can inherit the mercurial.ui.ui class, override the
edit() method and pass instance of my class to mercurial.dispatch.dispatch().

I hoped that I can do the same with calling the manual merge utility (vim
with 3 tabs by default). And I was surprised that I can't. Instead of this
merge program is called in filemerge.py. So if I want to change the
behaviour of "merge" command I need to override much more than one method.

Is there any objective reasons for such structure? Maybe better to call the
merge program through something like ui.ui.manual_merge()?
