Not really about attachment vs inline. The first patch doesn’t have
author, commit message, etc. I’m fine with either attachment or inline
:-)

Thanks! I applied your patch. I made a little change to it so it’s more
idiomatic.

Elisp tip of the day: if you want to make a list of possibly nil objects
and don’t want nil’s in the list, you can use append. Basically change

(list a b c)

to

(append (and xxx (list a)) (and yyy (list b)) (and zzz (list c)))

If the condition aren’t met, eg, (and xxx (list a)) returns nil, append
just appends an empty list.
