You need not replace anything, just to try a library - just load it. If it
happens to help, then you can worry about how to replace what you have.

I have no idea what is in Aquamacs. I don't use Aquamacs, I don't have
access to an Apple machine, and I wasn't involved in adding my code to
Aquamacs.

If I had to guess, I'd guess that Aquamacs does something different with
these libraries and `after-make-frame-functions'. But that's just a guess
from ignorance.

I'm afraid I can't help you then. It works fine on other platforms. Perhaps
Aquamacs does something special in this regard. Perhaps someone who is
familiar with Aquamacs has a suggestion.

Perhaps it has to do with the order of the functions in
`after-make-frame-functions'. You might try changing the order or testing
without any other functions in that hook, besides `fit-frame'.

Perhaps it has to do with how Aquamacs and Apple create frames, and how that
process interacts with `after-make-frame-functions'. Dunno.

Did you say that it doesn't work only on files with long lines? Perhaps
`fit-frame' is in fact being called, but it doesn't do what you expect.
`fit-frame' does not fill or change your text in any way. The new frame
width is based on the longest line in your buffer, so if you have long
lines, then you'll have a wide frame. You can, however, control the maximum
width in various ways (variables) - see the Commentary in fit-frame.el.
