Count the number of commits that are reachable from start until a commit that is reachable from end is encountered. In other words, count the number of commits that are in start, but not in end.

Note that this method calls RevWalk.reset() at the beginning. Also note that the existing rev filter on the walk is left as-is, so be sure to set the right rev filter before calling this method.

Parameters:
walk - the rev walk to use
start - the commit to start counting from
end - the commit where counting should end, or null if counting should be done until there are no more commits
Returns:
the number of commits
Throws:
MissingObjectException
IncorrectObjectTypeException
IOException
