as I'm the one who use this feature for more than 7 years, I can only
object to this. I'm happy to have the confirmation dialog for the
whole-file revert (the current state) but having the dialog also for
partial revert would be too disruptive. And disabling both at the same
time would not be an option for me.

The thing is, that the partial revert "just don't happen by accident".
Here are the minimum user actions needed to get to this dialog:

1. whole-file revert

- do a Ctrl+J, more or less anywhere in the GUI

Hmm, have to agree with you on this. It is kind of easy to trigger. But
read below why I think partial reverts are just as easy to trigger.

2. hunk revert/revert one unselected line

- right click anywhere in the diff pane (thats around 60% of the window

area)

quoted

- move the mouse pointer down 3/4 menu items
- click this menu item

But what if you wanted to click "Stage hunk", and instead click "Revert
hunk" instead. This is what I mean by "accidentally".

This is even more a risk in the current layout of the buttons, which are
in the order:

Stage Hunk
Revert Hunk
Stage Lines
Revert Lines

but this is your current layout! my layout in the patch from 2012 was (and
still is in my git-gui):

Stage Hunk
Stage Line
----------
Revert Hunk
Revert Line


thats a separator inbetween!

 
Looking at how this discussion has been going, I see that people really 
don't like the dialog, even with a config option. So I will send a 
re-roll with this layout of buttons and ability to undo last revert. I 
hope that will satisfy most people.

In this layout, if you wanted to click Stage, you might end up clicking
Revert instead, losing part of your work. Even if we switch up the
layout a bit, I feel like the potential of "mis-aiming" your mouse is
there, but it can certainly be improved.

3. partially revert selected lines

- select some content in the diff pane by starting by pressing and
holding a left click
- end the selection by releasing the left click
- move the mouse pointer down 3/4 menu items
- click this menu item

Thats always at least 2 user actions more than the whole-file revert.
Thus this cannot happen by accident quite easily in comparison to the
whole-file revert. And thats the reason why this dialog exists, from
my point of view.

I can see the need to disable the dialog for the whole-file revert,
and IIRC that was also requested a long time ago on this list. But I
don't see a reason to have this dialog also for the partial reverts as
a safety measure.

I do (not too strongly, but I do), as I explained why above.

It shouldn't be too difficult to have separate knobs for whole-file and
partial reverts, but they will add two config options. Not necessarily a
bad thing, I just thought the people who wanted to disable partial
reverts would also want to disable whole-file reverts.

But I have another suggestion in mind. I'll reply to one of the other
emails in this thread about it. Please read it there, I'd rather not
type it twice.
