OFW debugger render issue with abort strings

Try debugging (boot-read) with the new, pretty OFW debugger where it shows the whole word definition in colours.

It seems to struggle with abort strings - hit space until you pass the first "abort" then you'll see that the "current word" cursor gets a bit lost and this makes debugging quite painful.

The real problem is not the abort string itself, but instead the fact that the string contains embedded CR-LF characters, which is stylistically unusual for Forth strings. Those embedded cursor motions bypass the mechanisms that work out screen placement.

I might not be fixing this anytime soon, as I don't really know an easy fix.

You can switch to old mode by typing 'v' (toggle "visual" mode). If you type 'h', the long-form help screen documents that character, as well as the 'l' character that redisplays the definition.
