Breadth pass for options not yet exercised:
output-options output shape of --version/--help/-i/-n/--stats/
--out-format/--list-only/-q/--progress/-h/-8 (these control
output, not path handling, so they're checked for shape).
compare -c and -I catch a stealth change (same size+mtime, new
content) deep in the tree; --size-only skips a same-size
change; --modify-window absorbs a 1s mtime difference.
compress-options --compress-choice for every advertised compressor,
--compress-level, --skip-compress, --checksum-choice for
every advertised checksum, and --checksum-seed -- each a
clean byte-identical transfer at depth.
Green on master and under --protocol=29/30.

"""Breadth coverage of the algorithm-selection options at depth:

--compress-choice / --compress-level / --skip-compress and

--checksum-choice / --checksum-seed.

Compression and checksum choice don't change the result, so each available

algorithm is exercised for a clean, byte-identical transfer of a >=3-deep tree

(proving the option parses, negotiates and doesn't corrupt data).
