py3: create built in exceptions with str type messages in win32.py I hit an IOError in unlink() in test-pathconflicts-basic.t, that then crashed as it was handled: File "mercurial\dispatch.py", line 359, in _runcatch return _callcatch(ui, _runcatchfunc) File "mercurial\dispatch.py", line 367, in _callcatch return scmutil.callcatch(ui, func) File "mercurial\scmutil.py", line 252, in callcatch ui.error(_("abort: %s\n") % encoding.strtolocal(inst.strerror)) File "mercurial\encoding.py", line 205, in unitolocal return tolocal(u.encode('utf-8')) AttributeError: 'bytes' object has no attribute 'encode'

tests: stabilize test-shelve.t#phasebased for #no-symlink and #no-execbit The rev number ended up being 11 instead of 13 on Windows. If I ever get back to issue2020, this will go away.

debugdirstate: deprecate --nodates in favor of --no-dates We have supported 'no-' prefixes for boolean flag for a few years now, so I was expecting it to be --no-dates. I noticed that we have --nodates options for a few more commands (e.g. `hg diff`), but I'll leave that for another day. Differential Revision: https://phab.mercurial-scm.org/D4693
