Well, I have no clue why it's not working for me.

When I visit ChangeLog, Emacs has the following settings:

 C-h v buffer-file-coding-system RET
     buffer-file-coding-system's value is iso-8859-1
     Local in buffer ~/work/emacs/lisp/ChangeLog; global value is 
mule-utf-8
     Automatically becomes buffer-local when set in any fashion.

     Coding system to be used for encoding the buffer contents on saving.

 C-h v coding-system-for-write RET
     coding-system-for-write's value is nil

     Specify the coding system for write operations.

And if I don't set explicitly buffer-file-coding-system to 
iso-2022-7bit, I got an error.
The backtrace is:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
 fill-delete-prefix(101 #<marker (moves after insertion) at 125 in 
*Warning*> "  ")
 fill-region-as-paragraph(101 126)
 select-safe-coding-system(1 674433 iso-8859-1 nil 
"/home/vinicius/work/emacs/lisp/ChangeLog")
 write-region(1 674433 "/home/vinicius/work/emacs/lisp/ChangeLog" nil t 
"~/work/emacs/lisp/ChangeLog")
 basic-save-buffer-2()
 basic-save-buffer-1()
 basic-save-buffer()
 save-buffer(1)
 call-interactively(save-buffer)

Does anyone have a suggestion?
