Thanks for these patches, Austin. They are a definite improvement for
notmuch show code. I hope it would soon get pushed to master. And I
hope more patches would follow :)
Few minor comments below.

If I did not miss anything, attachment is used only as following:
attachment ? "attachment" : "part"
Please make it const char[] and set to "attachment" or "part".
> + notmuch_bool_t leaf = GMIME_IS_PART (node->part);
Please add const where possible to local variables (e.g. attachment, leaf).

Yay! Only one header-printing code left :)

I always forget about it, can we declare variables inside if condition
like in C++? I.e.:
if (const char *filename = leaf ? g_mime_part_get_filename (GMIME_PART
(node->part)) : NULL)
If yes, I would prefer to use this style where possible.

I would revert blank line changes. But I do not insist :)

This condition is repeated at least twice. Please consider moving the
message variable below to the top level and using it in the conditions.
