Files with trailing whitespace cannot be pushed to the hg cpython repository. For 3.x (on Windows), help.html is generated, after editing idle.rst in the earliest maintenance version, with sphinx-build -bhtml . build/html python_d.exe -c "from idlelib.help import copy_strip; copy_strip()" After refreshing TortoiseHG workshop to generate a diff, check both the diff and displayed text. Push the diff along with the idle.rst change and merge both into default (or an intermediate maintenance version). When the 'earlist' version gets its final maintenance release, do an update as described above, without editing idle.rst, to rebase help.html on the next version of idle.rst. Do not worry about version changes as version is not displayed. Examine other changes and the result of Help -> IDLE Help. If maintenance and default versions of idle.rst diverge, and merging does not go smoothly, then consider generating separate help.html files from separate idle.htmls.
