How to use meld with 'svn diff'

[Frederik Uppesen <f_uppesen yahoo com>]

'svn diff' can be used to do a variety of comparisons across branches and revisions.

But asking svn to use 'meld' in its config file (by setting 'diff-cmd') results in a lot of complaints from 'meld'!

(I know that 'meld' is svn-aware --- that's useful for simple comparisons.)

What's the trick? I must be missing a helper script?

thanks
