The source is backfill_tags() which, in future, resets some transport
options back to defaults. The current set_option() in there only deals
with booleans or number (depth). But in future it resets deepen-since,
which is a string.
I think the main reason is, we do not have a way to reset (or unset) a
transport option. Should I keep this commit and explain about this, or
have a new transport API to reset option?
