When in "message-mode" (the buffer I am composing this message in) and I
do C-h m I see the following at the top of the resulting "Help" buffer.
,---- C-h m
| Enabled minor modes: Auto-Composition Auto-Compression Auto-Encryption
| Auto-Fill Column-Number File-Name-Shadow Font-Lock Footnote
| Global-Font-Lock Gnus-Message-Citation Ido-Everywhere Iswitchb
| Line-Number Mml Mouse-Wheel Shell-Dirtrack Tooltip Transient-Mark
| Which-Function
`----
This suggests that you can steal some code from the C-h k C-h m .
M-x find-function RET describe-mode RET
