Subject: Use BABELTRACE_FORCE_COLORS environment variable to force color support
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=62128320f132f643c5d43fce0220531143614180;p=babeltrace.git

Use BABELTRACE_FORCE_COLORS environment variable to force color support

This allows this use case:

    BABELTRACE_FORCE_COLORS=1 babeltrace ... |& less -R

to see the logging's color in `less`.
