Rebase a simple DAG:
  $ hg init repo1
  $ cd repo1
  $ hg debugdrawdag <<'EOS'

Write files to the working copy, and ensure they're still there after the rebase
  $ echo "abc" > a

Add an explicit test for rewrite_hash_refs when the detected prefix is
ambiguous. Here's the super low-tech way I found this collision, if the hashing
scheme ever changes:
# hg init
# echo test0 > test
# hg ci -qAm 'test0' -u 'test' -d '0 0'
# i=1
# while [[ $(chg log -r . -T'{shortest(node, 6)}' | wc -c) -eq 6 ]]; do
#   chg co -r 0000000000
#   echo "test$i" > test
#   chg ci -qAm "test$i" -u test -d '0 0'
#   (( ++i ))
# done
  $ hg co -q 0000000000
  $ echo test5281 > test
  $ hg ci -qAm 'test5281'
  $ hg co -q 000000000
  $ echo test9912 > test
  $ hg ci -qAm 'test9912'
  $ hg co -q 4
  $ echo contents > some_file
  $ hg ci -qAm 'The previous two (parentless) commits had a hash prefix of b04363. Check that rewrite_hash_refs will not fail because of that.'

Test (virtual) working directory without changes, created by merge conflict
resolution. There was a regression where the file was incorrectly detected as
changed although the file contents were the same as in the parent.
