Subject: [PATCH] Unify prompt for gnupg passphrase between GNU/Linux and
 Windows.

* lisp/epg.el (epg--start): Use `raw-text' for coding system instead
  of binary in order to avoid spurious carriage return on Microsoft
  Windows and DOS when prompting for a password.

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