It's not an example, it's kind of a worst case scenario if there's no
easy and safe way way to enable synchronize_flags.  I want to try
disabling flags, but if I change my mind and the only way to get it back
is to do a full notmuch dump/restore, that's a pretty hefty penalty.
Also, even if I do a full notmuch dump / restore, I'm not sure if the
notmuch new is necessary in the middle.

So my question remains, what's the easiest safe way to re-enable
synchronize_flags after disabling it?  (Safe meaning it won't change any
tags.)  It could be that there's a very simple answer, in which case
sticking it in the man page might be nice.

Thanks,
David
