In TortoiseSVN it's possible to view a revision's changes as a unified diff by right clicking it in the revision log, and clicking "show changes as unified diff". But that doesn't let me view my working copy's changes as a unified diff. Is it possible to do this somehow?
I also noticed I can right click in Windows Explorer and select TortoiseSVN->Create patch which does what I want, but it also saves the diff as a file which I don't want. I just want to view the diff.
I figured it out. In the Commit dialog, one needs to shift-select as many of the files as one wants, then right click and select 'show differences as unified diff'.
