Oh, I know. I wasn't talking about ripping *all* af it, just the part
where it retains the read-only bit on the destination.

If I consider that:
- svn:needs-lock was developed on *nix (linux, probably)
- in *nix it's possible to overwrite a read-only file
- unix retains the attributes on the file being renamed
- on Windows a file cannot be renamed if it or its rename-target is read-only
- svn_io_file_rename should behave the same on all platforms

I think that the change should not be ripped out, but has a bug: If it
were to remove the readonly bit on both files and put back
read-onlyness *of the source* it behaves the same on both *nix and
windows (instead of the current situation where it does the same
thing, but uses the target atts).

bye,

Erik.
