Well, the original issue said it was easy to reproduce, but didn't
give enough details to do it. I see no indication of which version of
Subversion was being used, and I don't know whether the URL being
copied was a file or directory, and if it was a directory what it
contained.

Using r5775 I can do the following

  rm -rf repo1 repo2 wc1 wc2

  svnadmin create repo1
  svn co http://localhost/tmp/repo1 wc1
  svn mkdir wc1/foo
  echo zig > wc1/foo/zig
  svn add wc1/foo/zig
  svn ci -m v1 wc1

  svnadmin create repo2
  svn co http://localhost/tmp/repo2 wc2
  svn mkdir wc2/bar
  echo zig > wc2/bar/zag
  svn add wc2/bar/zag
  svn ci -m v2 wc2

  svn cp http://localhost/tmp/repo2/bar/zag wc1/foo/zag2
  svn cp http://localhost/tmp/repo1/foo/zig wc1/foo/zig2
  svn cp wc1/foo/zig wc1/foo/zig3
  svn st wc1
  svn ci -m v3 wc1

and it doesn't hang the repositories. Both the URL->WC copies "work"
although neither appears to record the copyfrom history. So two
questions arise

Should I be able to copy a file into a working copy from an unrelated
repository?

If I copy a file from a repository into a working copy should it
record copyfrom history?
