Subject: [PATCH] bisect: check for mandatory argument of 'bisect replay'
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

'git bisect replay' has a mandatory logfile argument, but the current
implementation doesn't check whether the user has specified one.  When
the user omits the logfile argument, this leads to the following
unhelpful error message:

  cannot read  for replaying

So, check for the mandatory argument first, and provide a more
meaningful error message when it is omitted.
