grep: give different labels to + and - symbols I find it more useful to give different colours to plus and minus, but it's difficult to do so if the default output uses the same label for both. The following augments the names of columns with some extra labels, akin to the diff.inserted and diff.deleted labels for the diff command. This is done by adding an extra label field to the columns tuples.
