hm, but couldn't the indentation space be spoofed by a well-crafted
message? that is: a non-indented message will consume space up to (but
not including) the fringe. so a well-crafted message could be made to
*look* like an indented message, including whatever is comparable to the
chrome/UI elements we would use for an actual signed message.
I think it is also acceptable to just punt at some level -- we can say
"notmuch-emacs will indicate the outermost signed message part in the
fringe; it will not indicate nested signed messages in the fringe".
this is still an improvement from the status quo.
