Subject: Remove dead code from rfc2047
X-Git-Tag: emacs-26.0.90~870^2~30
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=3539657bb726b91f2bc475d4e1c5fe276feb064f;p=emacs.git

Remove dead code from rfc2047

* lisp/mail/rfc2047.el (rfc2047-fold-field): Remove dead code.

It's been disabled since 2005, when I made the change with the
following comment.

(rfc2047-encode-message-header): Disabled header folding -- not
all headers can be folded, and this should be done by the message
composition mode.  Probably.  I think.
