help: document color/pager pitfalls on Windows

Browse Source 
Even though I figured this out a few weeks ago, I was initially puzzled where
the color went when I upgraded to 4.2 on a different Windows machine.  Let's
point users reading the help into the right direction.

MSYS and Cygwin shells provide `less` as a pager, which can be configured to
support ANSI color codes. See :hg:`help config.color.pagermode` to configure
the color mode when invoking a pager.
You can disable the pager for certain commands by adding them to the
