[mm]: Regression-test Savannah #66439.
The bottom block feature BS/BE should work with LT letters.
* contrib/mm/tests/letter-with-bottom-block-works.sh: Do it.
* contrib/mm/tests/artifacts/letter_with_bottom_block: Add expected
rendering.
* contrib/mm/mm.am (mm_TESTS): Run test.
Test fails at this commit.

[mm]: Fix Savannah #66439 (BS/BE with LT).
* contrib/mm/m.tmac (BS, BE): Use box diversion instead of a regular one
to populate the bottom block. This fixes interaction of the bottom
block feature--when `BS` and `BE` are called prior to formatting any
other text--with `LT` letters specifically but might also resolve
other similar problems with BS/BE use. Using a regular diversion
moved the vertical drawing position from its "pre-page" location of
"-1" (because the `BS` macro called `br` to ensure that the bottom
block didn't absorb any partially collected line). That in turn
sprung the default header trap that writes a centered page number.
The `LT` macro is written such that if the drawing position is not at
the top of the page, it fails to format the pre-body letter material
(writer's address, date, inside address, salutation, etc.). (Because
the first page has already started and the drawing position was
non-negative, the `LT` macro was also too late to turn off the default
header on the first page.)
(BE): Annotate explicit `br` retained here; we don't want to
silently discard a partially collected line when closing the box
diversion. The document author should delete from a bottom
block any undesired content on a partially collected line.
