vimdiff wrapper for diff-cmd not working with 1.8

Hi there,

I just installed svn 1.8 on our cluster. Before, we used svn 1.7.9 and a little vimdiff wrapper (taken, with a few changes, from http://svnbook.red-bean.com/nightly/en/svn.advanced.externaldifftools.html#svn.advanced.externaldifftools.diff), which worked like a charm when called as "svn diff --diff-cmd=diffwrap.py filename". However, with svn 1.8 something seems to have changed:

The only lines I see after executing the command above are

> Index: filename
> ===================================================================

and the terminal hangs. When I enter ":qa!", I get the following line

> Vim: Warning: Output is not to a terminal

and I am back in the terminal. I have not changed anything in the wrapper script, and indeed, when I manually use it with our old svn version (1.7.9), it still works. Does anyone have an idea what has changed in the way the diff-cmd is invoked? And, more importantly, how I can change the vimdiff wrapper so it works again?

Regards,

Michael
