Minor glitch in 256-color xterm emulation

[ErnieLongmire]

In Beta 2 I'm seeing a minor glitch when running the xterm test script "256colors2.pl" (Google for links). ^[[48;5;124m displays as rgb(175,0,0) instead of rgb(127,0,0), and ^[[48;5;64m displays as rgb(95,135,0) instead of rgb(42,85,0). (Values are slightly different in the GIF below but you can see the cells with the problem.)
