The module_list_compute() function takes an argc/argv pair, but never looks at argc. This is OK, as the NULL terminator in argv is sufficient for our purposes (we feed it to parse_pathspec(), which takes only the array, not a count).
Note that one of the callers _looks_ like it would be buggy, but isn't: we pass 0/NULL for argc/argv from module_foreach(), so finding the terminating NULL in that argv naively would segfault. However, parse_pathspec() is smart enough to interpret a bare NULL as an empty argv.
