[PATCHv3 6/7] Add new fast-export testcases

[newren@gmail.com]

From: Elijah Newren <newren@gmail.com>

The testcases test the new --tag-of-filtered-object option, the output
when limiting what to export by path, and test behavior when no
exact-ref revision is included (e.g. master~8 present on command line
but not master).

Signed-off-by: Elijah Newren <newren@gmail.com>
---
Since the last series, one new testcase was added to document that running
with arguments like 'master~3' or 'master~7..master~2' are still broken.
