run-tests: support running tests in parallel on windows Previously, we used os.spawnvp, which doesn't exist on Windows, and isn't needed anyway (the command line begins with an absolute path). We also need a slightly more convoluted way to wait for processes without specifying an order on Windows, as it lacks os.wait.

makefile: allow local builds to work on windows/mingw32

check-code: make 'missing whitespace in assignment' more aggressive New warnings: > a.b=ab missing whitespace in assignment (the pattern did not accept '.' on the left hand side) > a=a missing whitespace in assignment (the right hand side pattern never matched a single character) > a=a + 7 missing whitespace in assignment (the pattern only matched one character after the identifier following =)

check-code: there must also be whitespace between ')' and operator The check pattern only checked for whitespace between keyword and operator. Now it also warns: > x = f(),7 missing whitespace after , > x = f()+7 missing whitespace in expression

rm: drop misleading 'use -f' hint for the rm --after 'not removing' warning A warning mentioning 'forgetting' or 'recording delete' would be more correct than 'not removing' but also more confusing.

contrib: state explicitly how hgtest.vim can be installed

tests: kill daemons early, making breaking at "Accept" prompt safe

run-tests: use correct python safely under --jobs

run-tests: check for the correct python when starting

run-tests: use correct python when run with --local
