[ Overview of SVN 1.7's 'patch' command ]

Stefan, thank you for that overview!

I have a question that touches that topic and which I stumbled over sometime
in the past about possible sources and targets of merge operations:

1. Source being a working copy with modifications.
The idea is to use this to shelf some changes. I simply copy a few files with
changes inside a working copy without committing them and then revert the
changes on the original to first pursue another line of development. When I'm
done, I'd like to merge the changes back into the "real" target files and
revert the copy operation.

  edit x # start cool feature
  # ...oh wait, need something else first!
  svn copy x x.shelved
  svn revert x
  edit x # do something else
  svn commit x -m "something else"
  svn merge x.shelved x # *Fictional command!*
  svn revert x.shelved
  rm x.shelved
  edit x # continue cool feature

Note: I'm aware that I could create a feature branch which ideally would be
equivalent. However, that requires a connection to the repository (no offline
work) with write access (think about non-core developers trying to manage
patches) and adds noise to the commit logs (think about changes which for
whatever reason you don't want to make public). Alternatively, I could use
svk, but that again is some software I have to install first.

2. Target being a non-working copy.
I don't remember where I wanted to use this one, I believe I wanted to apply
changes I made to an SVN vendor branch to a (non-versioned) release of that
vendor or to some code in a completely different VCS.

Cheers!

Uli
