tests: demonstrate how evolve loses transitive copies when interrupted Let's say `b` has been renamed to `c` in commit A and then renamed to `d` in commit B. We now modify A in a way that will cause a conflict when we evolve B. `hg evolve` will now stop and let the user resolve the conflicts, but it will have lost the copy information in the working copy (should still be c->d).

Testing the continue functionality of `hg evolve`

  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > interactive = True
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Setting up the repo

  $ hg init repo
  $ cd repo

  $ hg add .hgignore
  $ hg ci -m "added hgignore"
  $ for ch in a b c d; do echo foo>$ch; hg add $ch; hg ci -qm "added "$ch; done
