[PATCH 12/12] misc *.c: use designated initializers for "partial" struct assignments

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change a few existing non-designated initializer assignments to use
"partial" designated initializer assignments. I.e. we're now omitting
the "NULL" or "0" fields and letting the initializer take care of them
for us.
