Revert "filter-branch: subdirectory filter needs --full-history"
This reverts commit cfabd6eee1745cfec58cfcb794ce8847e43b888a. I had
implemented it without understanding what --full-history does. Consider
/ / /
where B and C modify a path, X, in the same way so that the result is
identical, and D does not modify it at all. With the path limiter X and
without --full-history this is simplified to
i.e. only one of the paths via B or C is chosen. I had assumed that
--full-history would keep both paths like this
removing the path via D; but in fact it keeps the entire history.
Currently, git does not have the capability to simplify to this
intermediary case. However, the other extreme to keep the entire history
is not wanted either in usual cases. I think we can expect that histories
like the above are rare, and in the usual cases we want a simplified
history. So let's remove --full-history again.
(Concerning t7003, subsequent tests depend on what the test case sets up,
so we can't just back out the entire test case.)
