Merge branch 'of/bundle-uninitialized-memory-fix' into seen

The 'git bundle create' command has been updated to initialize the
revs_copy structure at declaration. This prevents a potential crash
caused by reading uninitialized stack memory during cleanup when an
unrecognized argument is provided.

* of/bundle-uninitialized-memory-fix:
  bundle: do not free uninitialized memory on bad arguments
