Hello everyone,
I've noticed an anoying problem when I need to decrypt a file from Emacs
on Windows. The prompt asking my passphrase is two lines whereas on
Gnu/Linux it's only one.

I've tracked this bug down to the epg--start fuction and try the
attached patch from some time now without noticing anything wrong.

The step to reproduce the bug are below:
1) Start Emacs with: emacs -Q
2) Execute the following commands in scratch buffer
   #+BEGIN_SRC emacs-lisp
(require 'epg)
(setq epg-gpg-program "gpg2"
epa-pinentry-mode 'loopback)
;; open a gnupg encrypted file :
(find-file "~/.emacs.d/authinfo.gpg")
   #+END_SRC

The result vary between Emacs on Microsoft windows and on GNU/Linux.

On Microsoft Windows:
#+BEGIN_VERSE
Passphrase for 7F4B4084DFC4EBD2 Pierre Téchoueyres <pierre.techoueyres@free.fr>
:
#+END_VERSE
Note the cariage return before the colon.

On GNU/Linux:
#+BEGIN_VERSE
Passphrase for 7F4B4084DFC4EBD2 Pierre Téchoueyres <pierre.techoueyres@free.fr>:
#+END_VERSE

Thanks.

I think a better solution is to use raw-text-unix on both Unix and
DOS/Windows.  Can you try that and see if doing so produces good
results on both systems?

Hello Eli,
I first tried your solution, but that didn't work as expected. Then I
tried using 'raw-text unconditionnaly and everything seems to work as
expected on Microsoft Windows and GNU/Linux.

I do as follow because I think that '(raw-text . raw-text) is the same
as 'raw-text for the :coding keyword.

-				  :coding '(binary . binary)
+				  :coding 'raw-text

Should I prepare an ammended patch ?

Doesn't

                                  : coding 'raw-text-unix

work on both Windows and GNU/Linux?  Because I don't really understand
what "unconditionally" means in this context: I didn't suggest using
any conditions.

Thanks.

No it doesn't on Windows. I guess it's because of the -unix part which
results in adding the CR before the colon (:).

Sorry, when :coding 'raw-text-unix didn't work as expected I first try

:coding (if (memq system-type '(ms-dos windows-nt))
             'raw-text-dos
         'raw-text-unix)

then I realized it was equivalent to :
:coding 'raw-text

Right, I was confused and forgot that this was exactly the original
problem.  So raw-text it is.  And yes, please prepare a patch.

Actually, no: it isn't equivalent.  Just raw-text tells Emacs to use
the default on encoding (thus -dos on Windows and -unix on GNU/Linux),
and to _detect_ the EOL format on decoding.  But I don't think this is
a problem in this case, is it?

No, it isn't a problem, and on the contrary it's exactly what I want :
detect the EOL format for decoding.
