From: Nikolay Edigaryev <edigaryev@xxxxxxxxx>
'--filter=blob:limit=<n>' was introduced in 25ec7bcac0 (list-objects:
filter objects in traverse_commit_list, 2017-11-21) and later expanded
to bitmaps in 84243da129 (pack-bitmap: implement BLOB_LIMIT filtering,
2020-02-14)
The logic that was introduced in these commits (and that still persists
to this day) omits blobs larger than _or equal_ to n bytes or units.
However, the documentation (Documentation/rev-list-options.txt) states:
>The form '--filter=blob:limit=<n>[kmg]' omits blobs larger than n
bytes or units. n may be zero.
Moreover, the t6113-rev-list-bitmap-filters.sh tests for exactly this
logic, so it seems it is the documentation that needs fixing, not the
code.
This changes the explanation to be similar to
Documentation/git-clone.txt, which is correct.
