branch: master
commit 29c91f781c8ef00f12e7d591272561ade281bed7
Author: Paul Nelson <[email protected]>
Commit: Eli Zaretskii <[email protected]>

    Disable 'auto-mode-alist' during M-x rmail
    
    * lisp/mail/rmail.el (rmail): Bind 'auto-mode-alist' to nil
    while visiting the Rmail file, so that filename-based major mode
    selection does not invoke 'rmail' recursively.  (Bug#81368)
