Emacs does this if you configure it this way. I teached my emacs
_not_ to do this. BTW: I don't like to rely on the tools (editor is
just _one_ tool!) for doing the right thing.

But maybe we could find a compromise anyway. What about the following
proposal:

"svn co" behaves as it always has. So people do not need to change
their habits as long as they have plenty of disk space.

In contrast, "svn co --read-only" (or "svn co --hard-link") would
create hard-linked files which are set read only. This would keep you
from changing .svn/foobar files by accident. To change a specific
file or directory, you would issue "svn edit foobar", which actually
would do something like "rm foobar; cp .svn/foobar .; chmod +w foobar".

IMHO, this would give us best of both worlds:
- People with plenty of disk would never mind. The default would
  behave as it ever has.
- People who care about disk would "svn co --read-only" and
  "svn edit foobar" (they are already used to "xyz edit foobar" if
  they used perforce/clearcase before).

Comments?
