"ssh will drop" is inacurate

Several locations in the documentation there is phrases like this:
  On /etc/init.d/ufw start and 'ufw enable' the chains are flushed, so ssh will
  drop. This is needed so ufw is in a consistent state. Once the ufw is 'enabled'
  it will insert rules into the existing chains, and therefore not flush the
  chains (but will when modifying a rule or changing the default policy).

While it *may* cause ssh to drop, it is by no means a foregone conclusion.
I suggest this is changed to "may cause ssh to drop" (i'm happy to provide a patch if required).
