this benefit bugs you, you may add extra files to use up the space

I'll guess some figures about the *actual* NTFS overhead should help to
understand how bad the space problem is under Windows.

Anyway as many people pointed out, going to a single compressed file for
metadata is not cheap (dev may be cheap but finding/testing or
implementing the compression library won't be cheap) and may (will?) cause
serious performance problems. Now since "disk space is cheap", should the
subversion devellopment go into this difficult path to save some KBytes on
multi GBytes drives as most PC are currently equiped with.

In my opinion this only case where the .svn paradigm cause a significant
waste of disk space is for large binary files. Unfortunatly, this issue
will probably not be solved with the single compressed file metadata
