We have long allowed users to run e.g.
git log --ancestry-path master..seen
which shows all commits which satisfy all three of these criteria:
* are an ancestor of seen
* are not an ancestor of master
* have master as an ancestor
This commit allows another variant:
git log --ancestry-path=$TOPIC master..seen
which shows all commits which satisfy all of these criteria:
* are an ancestor of seen
* are not an ancestor of master
* have $TOPIC in their ancestry-path
that last bullet can be defined as commits meeting any of these
criteria:
* are an ancestor of $TOPIC
* have $TOPIC as an ancestor
* are $TOPIC
This also allows multiple --ancestry-path arguments, which can be
used to find commits with any of the given topics in their ancestry
path.
