Preserve metadata when staging a new version of an annexed file.
Performance impact: When adding a large tree of new files, this needs
to do some git cat-file queries to check if any of the files already
existed and might need a metadata copy. I tried a benchmark in a copy
of my sound repository (so there was already a significant git tree
to check against.
Adding 10000 small files, with a cold cache:
before: 1m48.539s
after: 1m52.791s
So, impact is 0.0004 seconds per file added. Which seems acceptable, so did
not add some kind of configuration to enable/disable this.
