When I start emacs as this:

% emacs -Q

and type:

  ESC : (text-scale-adjust 1) RET C-b

"(2)" is shown in the echo area.

With a file "~/temp" that contains only "abc\n", when I
start emacs as this:

% emacs -Q ~/temp

and type:

  ESC : (text-scale-adjust 1) RET C-f

"(6)" is shown.  When I type C-e instead of C-f above, "(5)"
is shown.  It seems that the number shown corresponds to the
character code of the last command.

This happesn both with emacs-23 and trunk branches.

That's because text-scale-adjust does at its end

    (push ev unread-command-events)))

and `push' returns its first argument.

Ah, I see.  Thank you for the explanation.  I didn't realize
that when I typed C-f (or C-b), text-scale-adjust was not
yet finished.  It would be better that read-event call in
text-scale-adjust has some prompt:
 e.g. (read-event "+,-,0 for further adjustment: ")

Anyway, I'll close this bug.

For non-interactive use, you should probably also be using
`text-scale-set' or `text-scale-increase' instead.
