This command is probably the first one that operates on a repository other than the_repository, in f9ee2fcdfa (grep: recurse in-process using 'struct repository' - 2017-08-02). An explicit 'struct repository *' was added in that commit to pass around the repository that we're supposed to grep from. Since 38bbc2ea39 (grep.c: remove implicit dependency on the_index - 2018-09-21). 'struct grep_opt *' carries in itself a repository parameter for grepping. We should now be able to reuse grep_opt to hold the submodule repo instead of a separate argument, which is just room for mistakes. While at there, use the right reference instead of the_repository and the_index in this code. I was a bit careless in my attempt to kick the_repository / the_index out of library code. It's normally safe to just stick the_repository / the_index in bultin/ code, but it's not the case for grep.
