Subject: emacs: override enriched-decode-display-prop for text/enriched display
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9b0582383833c323b0b902dbe21ecf9cb0cce628;p=notmuch.git

emacs: override enriched-decode-display-prop for text/enriched display

Switch to a local version of enriched-decode-display-prop if we
encounter a text/enriched part. This is to mitigate
https://bugs.gnu.org/28350. Normally it would be prudent to remove the
override afterwards, but in this case just leave it in.

Notes from db:
      This doesn't disable text/enriched, just one feature of it.
