However, some code may have only a pointer to such a struct which may be NULL (because _their_ callers didn't care about filtering, either). Rather than forcing them to handle this explicitly like: if (filter_options) traverse_commit_list_filtered(filter_options, revs, show_commit, show_object, show_data, NULL); else traverse_commit_list(revs, show_commit, show_object, show_data); let's just treat a NULL filter_options the same as LOFC_DISABLED. We only need a small change, since that option struct is converted into a real filter only in the "init" function.
