notmuch-show can be slow displaying large attachments so hide them by
default. The default maximum size is 10000 bytes/characters but it is
customizable.
Note that notmuch-show-insert-bodypart is also called from the reply
code so we need to be a little careful.
---
This code is getting a little fragile -- there are quite a lot of
factors in deciding whether to show or hide a part and the code is
called from both show and reply -- but it seems to work. For testing I
suggest setting notmuch-show-max-text-part-size to something small
like 100 or 1000.
Best wishes
