kdesc --rewrite from the reflection klammerset; txt caption rules the block's width

Assembled from klammertext-dev e99530408517. The katom rewrite patterns
are rendered from ref/ (a table in dispatch order, patterns through @c),
the procedural listing having left mac/; a plain-text caption's rule is
as long as the table or listing it captions; the editor-support comments
name the tools' new dev/ location.
