[RFC] Alternative color configuration for dmesg

[Dragan Simic <dsimic@xxxxxxxxxxx>]

Hello,

I'd like to implement support for an additional, alternative way for the 
color configuration in the dmesg utility.  It would use an environment 
variable to store the color configuration, in a way rather similar to 
what grep(1) does using the GREP_COLORS environment variable.

The rationale behind this new feature is the ability to have everything 
contained in one's ~/.bashrc, for example, with no need for additional 
configuration files, which makes setting up, using and keeping multiple 
machines in sync much easier.  Of course, the current way of using 
configuration files to store the color configuration for dmesg would 
remain untouched, so everyone would be free to make a choice.

Would you, please, accept a patch that implements the above-described 
new feature?
