Please provide a flag setting to allow emerge to suppress ansi screen formatting characters. When you pipe emerge output to less or to a file, the output is really ugly. Example, emerge -n .... or emerge --noansi.
support for this exists by the following 2 methods: (1) export NOCOLOR=true (2) color is only enabled if sys.stdout isnt a tty see Bug 5714 if those requirements satisfy your needs, then please close the bug :)
