Refactor the "goto usage" pattern added in
cd57bc41bbc (builtin/multi-pack-index.c: display usage on unrecognized
command, 2021-03-30) to maintain the same brevity, but doesn't run
afoul of the recommendation in CodingGuidelines about braces:
When there are multiple arms to a conditional and some of them
require braces, enclose even a single line block in braces for
consistency[...]
Let's also change "argv == 0" to juts "!argv", per:
Do not explicitly compare an integral value with constant 0 or
'\0', or a pointer value with constant NULL[...]
I'm changing this because in a subsequent commit I'll make
builtin/commit-graph.c use the same pattern, having the two similarly
structured commands match aids readability.
