color: document that labels are used for colorizing text

It is a deeply hidden secret that it's possible to colorise so many
things with so many different labels. This is an attempt to document
this. The text is a bit long, but it seems as short as can be while
documenting everything. Perhaps it should be hidden under a --verbose
option.

also available. By default, the terminfo database is used to find the
terminal codes used to change color and effect.  If terminfo is not
available, then effects are rendered with the ECMA-48 SGR control
function (aka ANSI escape codes).

Default effects may be overridden from your configuration file::

  [color]
  status.modified = blue bold underline red_background
  status.added = green bold
  status.removed = red bold blue_background

Text receives color effects depending on the labels that it has. Many
default Mercurial commands emit labelled text. You can also define
your own labels in templates using the label function, see :hg:`help
templates`. A single portion of text may have more than one label. In
that case, effects given to the last label will override any other
effects. This includes the special "none" effect, which nullifies
other effects.

The following are the default effects for some default labels. Default
effects may be overridden from your configuration file::

  [color]
  status.modified = blue bold underline red_background
  status.added = green bold
  status.removed = red bold blue_background
