No apology needed. My fault for not noticing that.

After you load the *.el files with `load-file', do this (mentioned in the
file Commentary):

M-: (add-hook 'after-make-frame-functions 'fit-frame)

If that doesn't fix the problem, then take a look at the value of
`after-make-frame-functions'. If it contains more than just `fit-frame', try
setting it to nil (empty) and then adding `fit-frame' back again:

M-: (setq after-make-frame-functions nil)
M-: (add-hook 'after-make-frame-functions 'fit-frame)

The result should then be this:

C-h v after-make-frame-functions ==> (fit-frame)

Note: If there were additional functions, besides `fit-frame', in
`after-make-frame-functions', then there might be a good reason for them to
be there. ;-)

The above procedure is just to try to see if `fit-frame' does the right
thing at least when there are no other `after-make-frame-functions' present.
If it does, then there is likely interference among those functions. In that
case, you can try (starting with an empty list) adding them all back, in
different orders (e.g. try `fit-frame' first or last), to see if that helps.
You get the idea.

But see my previous reply about long lines. It sounds like this might just
be unrealistic expectations on your part. `fit-frame' makes the frame as
wide as its longest line, but it respects maximum limits that you can set.
See the `fit-frame' doc string.
