color: don't fail on error messages when no curses (issue4237) The error only occured when Python didn't have curses - such as on Windows and when Python was built without curses support. No curses can also be emulated by (re)moving .../lib/python2.7/curses/ from the Python installation. It is left as an exercise to figure out exactly what changed in Mercurial that triggered this error.
