Feature request: add preview settings everywhere

Check list

• I have read through the README
• I have the latest version of forgit
• I have searched through the existing issues

Idea

I worked on implementing #389, would like me to add something equivalent to forgit log and other commands ?

[ccoVeille]

Assign me the issue if you are OK with my ideas.

I will have to find something to avoid duplicating code, maybe something like what you did for the pager. I will figure it later, if you are OK with me implementing this

@ccoVeille Thanks for your input and your contribution. I like the idea and would gladly accept a PR introducing this setting for all preview functions instead of just for one (like now done in #389). So before merging that one, let's see if you find a general solution with useful code sharing.

@cjappl @wfxr @sandr01d What do you think?

[ccoVeille]

I'll wait for other contributors feedbacks. But OK, I can put everything together.

I'll need time of course

[ccoVeille]

But no matter, how I'll do it, it won't affect the variable and the result of the variable I added in #389. So from my perspective it can be merged now. But I'm OK if you want me to implement everything
