test-bundle2-format: force gc so a GeneratorExit will be thrown
PyPy has looser semantics than CPython for when a generator's close
method will be called. Forcing the gc causes it to be called at
the right moment.
fixbundle() {
grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory" | \
cat
