From: Jeff King <peff@xxxxxxxx>
In most callers, we have an actual list_objects_filter_options struct,
and if no filtering is desired its "choice" element will be
LOFC_DISABLED. 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.
