conflicts: make spacing consistent in conflict markers The way default marker template was defined before this patch, the spacing before dash in conflict markes was dependent on whether changeset is a tip one or not. This is a relevant part of template: '{ifeq(tags, "tip", "", "{tags} "}' If revision is a tip revision with no other tags, this would resolve to an empty string, but for revisions which are not tip and don't have any other tags, this would resolve to a single space string. In the end this causes weirdnesses like the ones you can see in the affected tests. This is a not a big deal, but double spacing may be visually less pleasant. Please note that test changes where commit hashes change are the result of marking files as resolved without removing markers.

rebase: move bookmark update to before rebase clearing Bookmark fixing should probably happen before the rebase starts to clean up, so let's move it before clearrebased. This will also help a future patch where we want to add more clear logic to the existing clear section.

setup: include a dummy $PATH in the custom environment used by build.py This is required for building with pypiwin32, the pip-installable replacement for pywin32.
