Colorized results cause file open problems

[cfeduke]

By default both ag and ack colorize their results on my terminal.

sack tries to open the colorized file name which includes escape characters and fails.

Running with the --no-color option works as expected.

Update: I see sack__os is initialized in ~/.sackrc but apparently sack isn't sourcing that file? In any case putting a manual sack__os=uname within the function to strip out escape code characters with sed also doesn't seem to work.
