commit 7e8050cc621f27002eaf1be8114dee2497beff91
from: Hiltjo Posthuma <hiltjo@codemadness.org>

Fixed OSC color reset without parameter->resets all colors

Adapted from (garbled) patch by wim <wim@thinkerwim.org>

Additional notes: it should reset all the colors using xloadcols().
To reproduce: set a different (theme) color using some escape code, then reset
it:

	printf '\x1b]104\x07'
