"default" in ~/.dialogrc

[sunnycemetery]

Hello.  Has the "default" keyword been removed from color definitions  
in ~/.dialogrc?  Example:

shadow_color = (default, default, off)

This now produces an "expected attribute value" error on my system  
(1:1.3_20191110), though it did not previously (1:1.3_20190808).   
I saw nothing in CHANGES but would like to confirm before bugging the  
holier-than-thou maintainers of the distro from which the affected system  
pulls... though the following commit admittedly looks a little suspect:

Thank you.
