Cool, thanks for all the info!

Lazyness. Perhaps also because patch can't handle a few SVN-specific things
like tree changes or diffs in non-text files, at least not as well as SVN
does.

Well, even if it doesn't know how to tell the VCS about the added file, it
could at least add/delete/move the file and leave the rest to the user. I
don't expect SVN to do all work for me, but if it can apply a patch to a
working copy, why not to a non-working copy if the user asks for it? Yes, I
can probably do the same by piping "svn diff" into "patch", but firstly I
don't always have patch, secondly I can never remember its syntax and thirdly
it is of limited use sometimes.

Thank you!
