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.
