mq: use util.unlink instead of os.unlink and os.removedirs
If, on Windows, your repository and working copy are in a reparse point and you
use os.removedirs, you will remove non-empty reparse points, disabling the
reparse point. See @
fa901423ac23.
color: add support for Windows consoles
Introduces color.mode configurable with values 'auto', 'ansi', or 'win32'. Any
other value disables coloring. When 'auto' is selected, the win32 console
method will be used if the win32console Python module is detected (requires
pywin32 to be installed).
