I'm not arguing against the end-result here (an interactive guide to the effects of your entered regexp), but it strikes me as intensely confusing to use the standard completing read mechanism (or a variant of it) to read one thing (a regexp) while providing "completion" on another (face names). As a silly example, suppose a face name contained the character $: then selecting it from *Completions* (because you realized you wanted just that one) would have entirely the wrong effect. In general, then, this process probably deserves another name than "completing-read". It's related to re-builder, in that it is interactive "explanation" of a regexp; perhaps it could be called "building-read" or so? Davis -- This product is sold by volume, not by mass.
