If backtrace (in openmcl, at least), if you have a string argument that has a linefeed then then the linefeed messes up the display of the backtrace. Ideally I think it would be nice to replace the linefeeds with a special glyph (which I don't know how to do), but failing that I'm inclined to replace them with the string <<lf>> or \n or somesuch. Is anyone else bothered by this problem and/or have a better solution?
