Subject: [RFC PATCH] gnus: Add piem-gnus-mid-to-thread
Date: Mon, 18 Jan 2021 11:34:03 +0100	[thread overview]
Message-ID: <dde16a7a7a212e0947fdf3afad5678bac7ad2690.1610964014.git.public@yoctocell.xyz> (raw)

Inserts a string of the whole thread in mbox format.

The function works as expected when running
'M-: (funcall (piem-gnus-mid-thread t))', but when running
piem-b4-am-from-mid interactively, it just inserts an empty string.

Any ideas of why this happens?  Sorry, my elisp skills are not that great.
