contrib: add editmerge version for powershell This just adds a translation of existing contrib/editmerge to powershell. It allows users on Windows to iteratively resolve conflicts in their editor of choice. # no-check-commit

run-tests: allow hg executable to be hg.exe When running tests on Windows (via msys), user sometimes does not want to run them against source hg, but against compiled hg.exe. For that purpose, --with-hg option can be used, but currently run-tests.py prints a warning if the value of this argument is not a file with basename 'hg'. This patch allows such file to be 'hg.exe'.

obsolete: add operation metadata to rebase/amend/histedit obsmarkers By recording what operation created the obsmarker, we can show very intuitive messages to the user in various UIs.
