The parameter given must be usable as a single, valid
object name. Otherwise barf and abort.
+-q, --quiet::
+ Only meaningful in `--verify` mode. Do not output an error
+ message if the first argument is not a valid object name;
+ instead exit with non-zero status silently.
+
--sq::
Usually the output is made one line per flag and
parameter. This option makes output a single line,
Each line of options has this format:
------------
-<opt_spec><arg_spec>? SP+ help LF
+<opt_spec><flags>* SP+ help LF
------------
`<opt_spec>`::
is necessary. `h,help`, `dry-run` and `f` are all three correct
`<opt_spec>`.
-`<arg_spec>`::
- an `<arg_spec>` tells the option parser if the option has an argument
- (`=`), an optional one (`?` though its use is discouraged) or none
- (no `<arg_spec>` in that case).
+`<flags>`::
+ `<flags>` are of `*`, `=`, `?` or `!`.
+ * Use `=` if the option takes an argument.
+
+ * Use `?` to mean that the option is optional (though its use is discouraged).
+
+ * Use `*` to mean that this option should not be listed in the usage
+ generated for the `-h` argument. It's shown for `--help-all` as
+ documented in linkgit:gitcli[5].
+
+ * Use `!` to not make the corresponding negated long option available.
The remainder of the line, after stripping the spaces, is used
as the help associated to the option.
