add recompile comment in --trace-compile in terminal color mode too

Update: Just adds the comment in color terminal mode too

I didn't think adding the # recompile text to the end in the repl was a good idea as it increases likelihood of text wrapping.
And the color should be sufficient for local review, but when people copy from a color terminal we lose the recompile info.

So this just adds a zero-length change indicator, for people to look out for.

I think we should just add "# recompile" always. I was confused about what the coloring meant when I first saw it anyway.

Adding another symbol just makes it more confusing IMO

[IanButterworth]

Okay. Yeah

Thanks, @IanButterworth !
