Interesting. Did this actually cause problems in the wild? Just
being curious.
The return values from toggle_maintenance() and add_or_remove() are
what scalar.c::run_git() returns, which in turn come from
run_command() and eventually come from wait_or_whine(), so it very
well can be a positive non-zero value that signals a failure. It is
good to be prepared to see not just negative values but also
positive ones.
