Three random points:

 * A single output format can never be favourite of everybody, so
   this needs to be more like

	$ git branch --format='%(committerdate) %(refname) %(subject)'

   optionally with branch.format configuration variable to let the
   user specify the default.

 * I am not sure if the "current" marker should be anywhere but the
   frontmost column in the recommended default.  The output from the
   command obviously is not meant for machine processing
   (e.g. sorting or grepping), so this point is minor, though.

 * I do not think the object name should take valuable screen real
   estate, again in the built-in default (I wouldn't mind people
   hurting themselves with their configuration at all ;-).  After
   looking at "git branch --pretty-long" output, people can give any
   command john.ta/bugfixes instead of e15c95e, no?
