------------------------------------------------------------
Well I assumed that it failed with an error about ancestry. Nope it just
chokes:
{noformat}
svn diff ^/a/b bar --show-copies-as-adds
svn: E200003: Delta source ended unexpectedly
{noformat}
Which is strange for a ra_local diff.

> Finally for some more fun you can actually segfault the client like so:

> svn rm bar
> svn ci -mm
> svn cp foo bar
> svn diff ^/foo bar
> {noformat}
> This might be related but I'm not sure yet.
> Doing the a wc to wc diff e.g. {{svn diff foo bar --show-copies-as-adds}}
> works as expected in all the above cases so if someone has ran into this
> issue they can do that.
