[PATCHv2 0/3] rebase-i: Ignore comments and blank lines among squash/fixup commands

Here is v2 of the patch (now patch series) for making "rebase -i" ignore comments and blank lines while it is processing blocks of squash/fixup commands.

Please note that this version applies to "next", not "master", because it depends on some changes to t/t3404-rebase-interactive.sh that were made in mh/rebase-fixup. (This dependency is superficial and could be removed if necessary.)

The first patch in this series is not essential to the functionality but I found it useful when debugging the tests.

Michael Haggerty (3):
  lib-rebase: Provide clearer debugging info about what the editor did
  lib-rebase: Allow comments and blank lines to be added to the rebase
    script
  rebase-i: Ignore comments and blank lines in peek_next_command
