And yet clearly you did get it to execute automatically, since it
sent the message "Ran align-window-right".

Replace that file with one that does _only_ what you are testing.
Adding something untested to a giant sack of eels is not the way
to test that something.  (No, I cannot know that MF-Init.el is a
sack of eels.  Just a hunch.)

You are doing too much to find out about your problem.  Why throw
this test in with changing the font, checking the phase of the
moon, and mailing your mom her horoscope? ;-)

According to your code, that could happen if the `selected-frame'
is not what you think it is.  Try adding a`message' call that tells
you what the selected frame is, and its displayed buffer etc.
IOW, find out what is going on.

When?  Via the command-line switch -l?  Or using M-x load-file?
Emacs startup is a whole sequence of events.  Only at a particular
point is anything displayed.  At that point there is a frame to
be selected and aligned, but not before.

I do not see the problem here (on MS Windows).

I put just (align-window-right) in an otherwise empty file foo.el
(so I don't have to set the environment var), and I ran
emacs -Q -l "c:\path\to\foo.el".  That should be pretty much
equivalent to loading foo.el as an init file.

The frame was right-aligned, and I got the message
"Ran align-window-right".  No problem.

Try that: get rid of everything extraneous from your .emacs
(comment it out).  If that works, then bisect your .emacs
recursively, to find out what was interfering with the right
behavior.

FWIW, the fact that the code you showed here includes a comment,
a key binding, and a function that picks up an environment
var, all of which are extraneous, is indicative of not trying
to pare this down, to debug it.  (You can do that before asking
here, for instance.)

`M-x comment-region', with a numeric and with a plain prefix arg,
is your friend.  Use it to locate a problem in any file you load,
including your init file.  I bind it to `C-x C-;', and I use it
all the time, to comment and uncomment a block of code.
