implemented -- "filename" is read only by ^@source_listing and "pattern" by

nothing at all -- and because a literal parameter's content begins at the first

A word or phrase displayed verbatim in a line. Like ^@code, its content is

LITERAL -- nothing in it is interpreted as Klammertext -- so it must be closed

with the named delimiter "c^@". ^@c is the in-line form and ^@code the block

form of the same thing; before 2026-08-16 this parameter was an ordinary

string, so a "^#" or a bare "^@" inside it was read as Klammertext and usually

failed the file, which is not what "verbatim" can mean.
