I think stating this in terms of defaults that aren't really defaults
is what makes this cumbersome.  What about something like

.B \-\-entire\-thread=(true|false)

If true, 
.B notmuch show
returns all messages in the thread of any message matching the search
terms, rather than returning only the matching messages.  For
.B --format=json
this defaults to true.  For other formats, this defaults to false.
