"Display the message MSG in a new buffer, and keep in sync with HDRSBUF.
|
|
'In sync' here means that moving to the next/previous message in
|
|
the the message view affects HDRSBUF, as does marking etc.
|
|
|
|
As a side-effect, a message that is being viewed loses its 'unread'
|
|
marking if it still had that.

Depending on the value of `mu4e-view-use-old', either use mu4e's

internal display mode, or a (by default) display mode based on
|

Gnus' article-mode."
