[Message part 1 (text/plain, inline)]

Tags: patch


This patch marks EWW buffers as untrusted. This helps protect users if they:

1. Open a file via EWW.
2. Switch to a different major mode for better highlighting/rendering.

I often do this myself when viewing org, markdown, emacs lisp,
etc. files with EWW.
