If in <programlisting> width="some-value" is specified, it won't be
rendered the same way having the <programlisting> within <programlistingco>
as without <programlistingco> as parent: the verbatim font size doesn't get
smaller with wider widths.
So I changed the following in my print/dbcallou.dsl:
(define ($callout-verbatim-display$ indent line-numbers?)
;aumueller: inserted from dbverb.dsl
(let* ((width-in-chars (if (attribute-string (normalize "width"))
(string->number (attribute-string (normalize "width")))
%verbatim-default-width%))
(fsize (lambda () (if (or (attribute-string (normalize "width"))
(not %verbatim-size-factor%))
(/ (/ (- %text-width% (inherited-start-indent))
width-in-chars)
0.7)
(* (inherited-font-size)
%verbatim-size-factor%))))
(vspace (if (INBLOCK?)
0pt
(if (INLIST?)
%para-sep%
%block-sep%))))
;aumueller: remove the old stuff
; (let* ((width-in-chars (if (attribute-string "width")
; (string->number (attribute-string "width"))
; 80)) ;; seems like a reasonable default...
; (fsize (lambda () (if %verbatim-size-factor%
; (* (inherited-font-size) %verbatim-size-factor%)
; (/ (/ (- %text-width% (inherited-start-indent))
; width-in-chars) 0.7)))))
(make paragraph
space-before: (if (INLIST?) %para-sep% %block-sep%)
space-after: (if (INLIST?) %para-sep% %block-sep%)
font-family-name: %mono-font-family%
font-size: (fsize)

start-indent: (inherited-start-indent)

) ;aumueller
