There is already an issue out there.

It sounds like you are going to work on a patch? That'd be cool. One
reason the feature does not exist is that Subversion does not expose
an API to us to generate a diff for a named set of files. We have an
open issue filed and are hoping it will make it in to 1.5. You are
correct that an alternative is that we run each diff individually and
then combine the results in a single file. You are more than welcome
to write that if you want. I would suggest doing it in
svnClientAdapter so that it looks like there is an API to Subclipse.
Then if Subversion does add the feature, the svnClientAdapter
implementation can just be simplified by letting JavaHL do more of the
work.
