I hesitated a bit to put the testcase in t9350-fast-export.sh instead of
t9300-fast-import.sh. However, this patch fixes a bug where
fast-export <args> | fast-import
accidentally munges data, and t9300-fast-import.sh has no calls to
fast-export while t9350-fast-export.sh has calls to both fast-export and
fast-import. If I should design a test for t9300-fast-import.sh instead
of (or in addition to) what I have here, let me know.
