Put the tektronix cursor color back as it started.

Operating System Commands

OSC 118 ST puts the color of the cursor in xterm’s Tektronix 4014 window, OSC 18, back as the terminal started it, undoing any change made with OSC 18 ; Pt ST. xterm resets it to the value it started with (ResetColorsRequest).

It takes no parameter. xterm ignores an OSC 118 that carries anything after the number, OSC 118 ; 1 ST say, as a malformed sequence (do_osc); an empty one, OSC 118 ; ST, is the same as none.

libghostty-vt has no such color, and ignores OSC 18 and OSC 118, so the case that asks is a known difference.
