This function returns whether or not the contents of oid constitutes an “asis” region. The function returns a 1 if the oid is an “asis” region or a 0 if the oid is not an “asis” region. If the oid argument is omitted, then the current oid of the current document is assumed.

An “asis” region is one where newlines in the document content are preserved and cause line breaks both in the Editor pane and in published output. A region is “asis” if the FOSI specified justification (that is, quadding) in effect is “asis”, or if the document is an untagged ASCII file.
