progressively coloring character instead of line output about grc HOT 4 OPEN

My fix for this in the meantime is to prefix my aliases with stdbuf -oL

@derimagia, that also does line buffering. So in case of traceroute, I have to wait for a node not responding the default 15" timeout interval for 3 probes, before the 3 asterisks are colourized red (see my first example above).

Sorry misunderstood since for me the traceroute didn't even buff per line before I changed it. Buffing per character would be really difficult to do since it relies on regex. Work may be easier but even then it's difficult

grc 1.9 buffers lines in my system (10.8.5) by default. I don't know if character buffering would be possible — anyway, gstdbuf doesn't accept less than 1 K/KB, in case that'd be an option.
