Merge branch 'tb/pseudo-merge-bitmap-fixes'
We created a useless pseudo-merge reachability bitmap that is about
0 commits, and attempted to include commits that are not in packs,
which made no sense. These bugs have been corrected.
* tb/pseudo-merge-bitmap-fixes:
pseudo-merge.c: ensure pseudo-merge groups are closed
pseudo-merge.c: do not generate empty pseudo-merge commits
t/t5333-pseudo-merge-bitmaps.sh: demonstrate empty pseudo-merge groups
pack-bitmap-write.c: select pseudo-merges even for small bitmaps
pack-bitmap: drop redundant args from `bitmap_writer_finish()`
pack-bitmap: drop redundant args from `bitmap_writer_build()`
pack-bitmap: drop redundant args from `bitmap_writer_build_type_index()`
pack-bitmap: initialize `bitmap_writer_init()` with packing_data
