color: add win32 support for non-black background
This complicates the code a bit, since attributes need to be masked together
correctly before they are applied. Perhaps the code should be redesigned at
some point, but this works well for now.

'''track a line of development with movable markers
Bookmarks are local movable markers to changesets. Every bookmark
points to a changeset identified by its hash. If you commit a
changeset that is based on a changeset that has a bookmark on it, the
bookmark shifts to the new changeset.
It is possible to use bookmark names in every revision lookup (e.g.
:hg:`merge`, :hg:`update`).
By default, when several bookmarks point to the same changeset, they
will all move forward together. It is possible to obtain a more
git-like experience by adding the following configuration option to
your configuration file::
[bookmarks]
track.current = True
This will cause Mercurial to track the bookmark that you are currently
using, and only update it. This is similar to git's approach to
branching.

Bookmarks are pointers to certain commits that move when

You can use :hg:`bookmark NAME` to set a bookmark on the working
