Fix simple-modline--format in olivetti-mode

[duckwork]

olivetti-mode adjusts the window margin, which pushes the right segment of the modeline with simple-modeline to the left. At least for me.

After a little experimentation I've found that adding (- 0 right-margin) to the simple-modeline--format function adjusts the spacing for olivetti-mode.

I tried (- right-margin) but that doesn't work for some reason. I've also done very minimal testing, so it might not work everywhere.

I experience the same for "visual-fill-mode"!
Will try to test this the upcoming days, I am still not sure how to do it the right way with "straight.el" packaging and a bit afraid to break stuff^^

@florhizome iirc you can just go to the repo in straight/repos and edit it. If you want to make your own fork you can add the :fork directive to the straight recipe you use, so it'd look something like

(straight-use-package '(visual-fill-column 
                        :host github
                        :repo "joostkremers/visual-fill-column"
                        :fork "florhizome/visual-fill-column"))

... that is, until it's accepted upstream ^_^

I know of that but I actually don't want to fork everything myself just to be able to use a patch someone else has applied. Most of the time it's only temporary, until things get merged/fixed upstream and I prefer not having to clutter my repo with forks everytime I find a patch I want to try out. This has to be even more true for ppl that do more codework, you might want to just load a certain recipe to try it and inspect it, right?
It's interesting, if you too haven't really found how to do that. straight should support it, I think, it has all the capabilities needed, right?
but let's not get too far off topic :D

[florhizome]

It would be interesting to generalize this for any modeline or "normal modeline", to be able to add it to olivetti-mode and visual-fill-mode, since it would cover more ground there.at least for the default modeline i have the problem, too.

@florhizome I'm not sure what you mean -- my patch works with or without olivetti-mode, and should work in visual-fill-column-mode as well; I haven't tried it with the latter but it should Just Work®
