encoding: use hint markup for "please check your locale settings"
This will also make test-encoding.t pass on windows. The test would hit some
other code path that already used hint markup.
tests: make simple single quotes work with dummyssh on windows
Mercurial assumes that the shell on remote servers over ssh servers uses unix
quoting rules. Tests using dummyssh are however also run on windows where cmd
doesn't parse single quotes like on unix.
This hack replaces the single quotes with double quotes on windows - that is
enough to make test-ssh.t pass after
d8fa35c28335.
tests: ensure platform independent revision hashes in test-notify.t
Makes the test pass again on windows after
ca572e94d8e7.
