Thanks Bart.
I've now applied this as well as your following patch to make vim call
"notmuch show" with the --entire-thread option. I also added support to
the emacs client to do the same, and I updated the notmuch man page to
document the option.
Finally, I noticed that not passing the --entire-thread option caused
"notmuch show" to lose all nesting and thread-ordering characteristics,
(even if display the entire thread incidentally). This came from calling
notmuch_query_search_messages (which doesn't do any threading) rather
than notmuch_query_search_threads. So I committed the patch below which
causes it to once again call search_threads and simply not display any
messages that don't match the search when called without
--entire-thread.
I'll be glad if you have any comments to share.

notmuch show: Preserve thread-ordering and nesting without --entire-thread
When "notmuch show" was recently modified to not show an entire thread
by default, it also lost all capability to properly order the messages
in a thread and to print their proper depth. For example, the command:
notmuch show thread:6d5e3e276461188c5778c9f219f63782
had dramatically different output than:
notmuch show --entire-thread thread:6d5e3e276461188c5778c9f219f63782
even though both commands were selecting and displaying the same set
of messages. The first command would diplay them "flat", (all with
depth:0), and in strict date order; while the second command would
display them "nested" (with depth based on threading), and in thread
order.
We now fix "notmuch show" without the --entire-thread option to also
display nested and thread-ordered messages.
If some messages in the thread are not included in the displayed
results, then they are not counted when computing depth values.
