I just remind why I was anxious about seeing this "final option name" 
discussion starting. It is because the topic is very complicated.

Topic 1

First, the usual pattern for option like 'curse' 'color' 'mouse' etc is 
to have three value.  "yes", "auto", "no" (yes/no can be true/false).

- yes: make this happen or die
- auto: try to make it happen and skip if you think it will fails
- no: skip this feature.

"yes" is important to have so that (1) people can bypass wrong 
detection, (2) people can have a plain crash to debug.

"auto" is usually the default value (of something enabled by default, so 
not yet).

Topic 2

Do we want this option to be called "curse", curse is a fairly clear 
term for people who have done terminal programming and ... that is about 
it. Should we find a better name and if so, which one? 'advanced' 
'fullscreen' ?

Topic 3

But actually, the question is a bit wider,

1) There will be other commands that could make use of curse (eg: 
histedit, annotate, evolution based history viewing, etc). Do we really 
want a global switch for all of them? How would that config work?

2) There will be likely other -interface- to do this chunk selection. A 
regular idea is to fire a merge tool up and let the used select the 
change through it (eg: base, result, allchange). So do we want a more 
versatile option. eg:

   chunkselector=text (default)

Some alternative option could event be also based on curse if someone 
comes with a better alternative.
