Subject: 26.3; ffap-rfc-path requires a method for the latest version of tramp
Date: Tue, 02 Jun 2020 12:00:57 +0100

The default value of ffap-rfc-path, set in
/usr/share/emacs/26.3/lisp/ffap.el.gz, is
"/anonymous <at> ftp.rfc-editor.org:/in-notes/rfc%s.txt". The method part of
remote file names is now mandatory in tramp (from Emacs 26.1 according
to /usr/share/emacs/26.3/etc/NEWS). ffap-rfc-path needs to be changed to
"/ftp:anonymous <at> ftp.rfc-editor.org:/in-notes/rfc%s.txt".

Recipe to demonstrate the problem:

Start emacs with "emacs -Q".

Type "RFC6214". Run ffap with "M-x ffap <return>". The minibuffer
contains

    Find file or URL: /anonymous <at> ftp.rfc-editor.org:/in-notes/rfc6214.txt

with the cursor after the last "/". Pressing "<return>" finds the
nonexistent file "/anonymous <at> ftp.rfc-editor.org:/in-notes/rfc6214.txt".

To fix:

Go back to *scratch* buffer with "C-x b <return>". Type
"M-x set-variable <return> ffap-rfc-path <return>". Retrieve current
value with "<down>", then "<right> <right> ftp:" so the minibuffer
contains

    Set ffap-rfc-path globally to value "/ftp:anonymous <at> ftp.rfc-editor.org:/in-notes/rfc%s.txt"

Type "<return>". Then run ffap again with "M-x ffap <return>". The minibuffer
contains

    Find file or URL: /ftp:anonymous <at> ftp.rfc-editor.org:/in-notes/rfc6214.txt

Type "<return>". Emacs loads the correct document.
