Subject: notmuch.el: Handle attached images via an external viewer.
X-Git-Tag: 0.1~92
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=2174adf374370135061bd80db21cbd43bbac95ab;p=notmuch.git

notmuch.el: Handle attached images via an external viewer.

We temporarily override the mm-inline-media-tests variable so that the
only parts inserted into the temporary buffer (and lost) are those
parts that the user has already seen in the notmuch-show buffer.

Anything else, (such as images), will now be left to be handled via
mailcap, just like other attachment types.
