Maybe I'm just unreasonably paranoid, but I don't think I could ever
trust that you'd never find an arbitrary separator in the data.  I
suppose if you scanned the files beforehand you could come up with
something guaranteed to be unique, but that seems like a pain (and
doesn't happen regardless in patch 9/9; it just uses
"--------------GITCATFILESEPARATOR-----------")  If I were committing to
SVN, it's sure not something I'd like to bet the integrity of my data
on.

I think a far more reasonable output format for multiple objects would
be something like:

<count> LF
<raw data> LF

Where <count> is the number of bytes in the <raw data> as an ASCII
decimal integer.

This is pretty much the spiritual analog to the fast-import "exact byte
count" data input format as well.
