diff --summarize does not support WC <-> URL

Is there any reason the diff --summarize option does not allow you to
compare your WC with a URL?

First off, I think the use case of wanting to see the differences
between your WC and a branch/tag is valid. Certainly in the case of a
full diff it is. I do not see why it would not be for summarize also.

Second, I am asking from a Subclipse perspective. We have always had
this problem that in order to use the Eclipse graphical compare tools
we have to let Eclipse do the compare. All we can do is give it the
revisions. When doing a compare of a tree, we have to give it the
contents of both sets of files.

Well, this week we have enhanced this to use diff --summarize to
"front-end" this process and determine which files are different. We
can then just feed those files to Eclipse, and we can even do it
"on-demand". The upside is that we can now offer a good, quick UI for
comparing branches etc.

The problem is this limitation of not being able to use the local WC
as that is one of our primary places in the UI for initiating the
option.

So, with that said, were there any technical reasons that this option
did not support the WC when it was added? I do not care about it for
a WC to WC diff, because I can just let Eclipse do that anyway. That
being said, a WC to WC diff seems legit for this API too.
