```
Check that we are configured to display colors in the given context when
the user specifies a format string of `%C(auto)`, instead of always
displaying the default color for the given context.  This makes
`%C(auto)` obey the `color=auto` setting and brings its behavior in line
with the behavior of `%C(auto,<colorname>)`.

This allows the user the ability to specify that color should be
displayed for a string only when the output is a tty, and to use the
default color for the given context without having to hardcode a
color value.

Looks obviously the right thing to do from a cursory read.
Missing sign-off?

Thanks.
