katom types from ref/ in groups, @table :leading in lines of text and :rulesep, @code under txt, one table style attribute, literal-klammer options (from dev 2e453744f5e9)

kdesc --katoms is Klammertext rendered from ref/, the types in titled groups,
with --katoms full for the regex column.  @table :leading L is L lines of the
surrounding text in html as in pdf (default 1), and :rulesep spaces the
horizontal rules.  The html table has one style attribute, so :column_width
fractions take effect again.  @code and @source_listing render in plain
text; captions are numbered per kind there, and a table needs no blank line
around it.  @c takes :nd, and an option-shaped word before a bar inside
literal code is code.
