Opening typescript file in DOS mode?

Opening typescript file in DOS mode?

[Roy Smith]

On unix, files normally have newlines as line terminators.  But, if you run 
the "script" command, you end up with CR-NL pairs, because it's grabbing 
the raw terminal output.

If I open the resulting typescript file in emacs, I see all the ^M's at the 
ends of lines (not fatal, but annoying).  Emacs will automatically open 
CR-NL files in DOS mode, but the first line ("Script started on Sun Mar 13 
08:59:06 2005") only has the raw newline, which seems to make emacs think 
it's a normal unix text file.

I can force emacs to open the file in DOS mode interactively (C-X RET c dos 
RET C-X C-F typescript RET), but that's a pain.  Is there any way to get 
emacs to read past the first line when deciding which mode to open the file 
with?

,----[ C-h v auto-coding-regexp-alist RET ]
| auto-coding-regexp-alist's value is
| (("^BABYL OPTIONS:[ 	]*-\\*-[ 	]*rmail[ 	]*-\\*-" . no-conversion))
|
|
| Documentation:
| Alist of patterns vs corresponding coding systems.
| Each element looks like (REGEXP . CODING-SYSTEM).
| A file whose first bytes match REGEXP is decoded by CODING-SYSTEM on 
reading.
|
| The settings in this alist take priority over `coding:' tags
| in the file (see the function `set-auto-coding')
| and the contents of `file-coding-system-alist'.
|
| You can customize this variable.
