It is not just a style change, and initializing a struct partially
initializes the rest of the elements to 0. That's not C99 specific
behaviour, though using the designated initializer to initialize .part
to -1 is.
All of these result in the same value for params:
notmuch_show_params_t params = { .part = -1 };
notmuch_show_params_t params = { 0, 0, -1 };
notmuch_show_params_t params = { 0, 0, -1, NULL, 0 };
notmuch_show_params_t params = { 0 };
params.part = -1;
IMHO the first is cleanest and unaffected by changes in
notmuch_show_params_t, though might be surprising if you're not (yet)
used to C99 designated initializers.
In any case, in the current implementation only .part and .cryptoctx are
initialized, and the rest of the fields are random. This needs to be
fixed one way or another.

Jani.
