No; because 'svn diff' hides differences in end-of-line style and
keyword expansions, it has to preprocess the files in the working copy,
and it sends those preprocessed files to the external diff wrapper.

We could theoretically skip that part for files that don't have
svn:eol-style or svn:keywords properties, but then the tool invocation
would be inconsistent.

Your best bet is to use an editor that has Subversion support built in.
