No worries, and thanks for continuing to engage with it.

I think the problem here is that `org-image-actual-width` is essentially
a global solution to a potentially local problem. I can't set
`org-image-actual-width` to nil for just one image.

Yep, sounds good.

I was torn on this as well. However, I ended up feeling that it would be
worse to duplicate the same information in two places. This requires
updating the information in two places instead of one, and, worse, the
documentation could easily diverge. Because the function isn't
public-facing, but the variable very much is, I felt it better just to
include the documentation for the variable.

I also don't think removing the documentation from the function is that
bad. A lot of what that function does is to follow what the variable
tells it to do. Again, the function won't be called directly by an
end-user, so requiring that the developer refer to other documentation
for understanding implementation details seems reasonable. Finally,
there are numerous functions in org that tell you to refer to
documentation elsewhere (especially defcustoms) for further information.

Anyway, I still feel that the earlier patch (before regex changes is the
right one). But, if you want me to revert the documentation removal from
the function I will.
