Regrettably (?), you can't use this to implement marquee.

But you can make your text black with a black background. Or re-order lines, which I suspect to be "fun" for git logs.

I think the most devious would be to simply move the cursor up one line. This would result in the 'git log' line being overwritten, and hiding the commit from casual scrutiny.

ANSI control characters include cursor positioning, so in theory you could implement marquee messages. The problem would be introducing delay. I don't recall if you can do that using ANSI. You can emulate it by doing repeated cursor repositioning, but that would be rendered so quickly that the commit message would have to be enormous to include any appreciable delay.
