bb62e0a99f hid --recursive from `git clone -h' with PARSE_OPT_HIDDEN,
but 5c387428f1 reverted that:
$ git checkout 5c387428f1~
$ make
$ bin-wrappers/git clone -h
...
-s, --shared setup as shared repository
--recurse-submodules[=<pathspec>]
initialize submodules in the clone
-j, --jobs <n> number of submodules cloned in parallel
...
$ git checkout 5c387428f1
$ make
$ bin-wrappers/git clone -h
...
--recursive[=<pathspec>]
initialize submodules in the clone
--recurse-submodules[=<pathspec>]
initialize submodules in the clone
...
The two options were then reordered by c28b036fe3 (clone: reorder
--recursive/--recurse-submodules, 2020-03-16), and this is where we are
today:
$ git clone -h
...
--recurse-submodules[=<pathspec>]
initialize submodules in the clone
--recursive[=<pathspec>]
alias of --recurse-submodules
...
Junio did mention[0] that --recursive was no longer in the manual, but
not that it was once hidden from the option list.
