run-tests.py: backout "don't use console for stdin when running in debug mode" f5842787a958 caused that some kind of interactive debugging no longer was possible - such as running hg with --debugger in a test run with run-tests.py --debug .

rebase: properly handle unrebased revision between rebased one With rebase taking multiple roots it is possible to have revision in the "rebase domain" not rebased themself. We do not want rebased revision above them to be detached. We want such revision to be rebased on the nearest rebased ancestors. This allows to preserve the topology of the rebase set as much a possible To achieve this we introduce a new state `revignored` which informs `defineparents` of the situation. The test in `test-rebase-obsolete.t` was actually wrote and his now fixed.

rebase: lose the comparison to `nullmerge` For a proper behavior of the `--rev` revision we will need another possible state for revision ignored by rebase. We alter the comparison to `nullmerge` to match this future lower state too.
