DESCRIPTION
-----------
output without getting confused e.g. by values that
contain line breaks.
+--get-colorbool name [stdout-is-tty]::
+
+ Find the color setting for `name` (e.g. `color.diff`) and output
+ "true" or "false". `stdout-is-tty` should be either "true" or
+ "false", and is taken into account when configuration says
+ "auto". If `stdout-is-tty` is missing, then checks the standard
+ output of the command itself, and exits with status 0 if color
+ is to be used, or exits with status 1 otherwise.
+
--get-color name default::
Find the color configured for `name` (e.g. `color.diff.new`) and
