Обсуждение: bms_prev_member won't work correctly if bitmapword is 64-bits

bms_prev_member mistakenly has a hardcoded 24 in the function. This
should really be BITS_PER_BITMAPWORD - 8 so that it is properly set to
56 if someone compiles with 64-bit bitmapwords.

The attached fixes this and also adds a test to exercise the function
a bit. [1] indicates there's currently no coverage of this function at
all.
