That's quite ingenious! (Also, turning off the warnings for the duration of processing to suppress the "can't break line" messages.) I tried prettyprinting this with dots instead of hyphens (like in the original example), and this turns out to be a bit more complex, because we have to chop off the hyphens to replace them with dots. (I fiddled around with .shc as well, but that still leaves getting rid of the spaces. Unfortunately, asciifying the hidden spaces brings them back.) Also, if we want to process more than one word at a time, we have to distinguish between inter-word and intra-word divisions. Nevertheless, it's still possible to do this with the help of a few diversions and traps, as in the attached example macros. It's somewhat hackish and perhaps not the most compact code possible, but at least it's reasonably easy to understand and to modify.
