   3# After setting the fake editor with this function, you can
   4#
   5# - override the commit message with $FAKE_COMMIT_MESSAGE
   6# - amend the commit message with $FAKE_COMMIT_AMEND
   7# - check that non-commit messages have a certain line count with $EXPECT_COUNT
   8# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
   9# - rewrite a rebase -i script as directed by $FAKE_LINES.
  10#   $FAKE_LINES consists of a sequence of words separated by spaces.
  11#   The following word combinations are possible:
  12#
  13#   "<lineno>" -- add a "pick" line with the SHA1 taken from the
  14#       specified line.
  15#
  16#   "<cmd> <lineno>" -- add a line with the specified command
  17#       ("squash", "fixup", "edit", or "reword") and the SHA1 taken
  18#       from the specified line.
  19#
  20#   "#" -- Add a comment line.
  21#
  22#   ">" -- Add a blank line.
