Hello Ævar, I have some query related to this method. I have implemented
the logic locally and tests are also passing. However, I think the test
you mentioned is only running against the builtin files and files that
are used in builtin commands (e.g. `diff.c`, `builtin/add.c` etc.). But
some files from `t/helper` (e.g. t/helper/test-run-command.c) also uses
parse option API and it seems that there are no test files (pardon me if I
am wrong) for checking `parse option usage strings check` for `t/helper`
test-tool commands.

E.g. `grep -r --include="*.c" 'struct option .*\[] = {$' .` command gives
the following output - 

./helper/test-parse-options.c:  struct option options[] = {
./helper/test-lazy-init-name-hash.c:    struct option options[] = {
./helper/test-serve-v2.c:       struct option options[] = {
./helper/test-simple-ipc.c:     struct option options[] = {
./helper/test-parse-pathspec-file.c:    struct option options[] = {
./helper/test-getcwd.c: struct option options[] = {
./helper/test-run-command.c:    struct option options[] = {
./helper/test-run-command.c:    struct option options[] = {
./helper/test-proc-receive.c:   struct option options[] = {
./helper/test-progress.c:       struct option options[] = {
./helper/test-tool.c:   struct option options[] = {

So, these files are using parse-options and there is a chance that in
future, usage strings from these files may violate the style guide. In
this case, all tests will be passing even if there are some style
violations. What do you think?

Thanks :)
