Specified by:

optNextLine in interface LineFeeder

Parameters:

atTop - Is this the beginning of a top-level unit (typically, a top-level expression)?

quoted - Will this next line be taken as literal text? If so, then it should not be trimmed or indented. 'quoted' is true between double quotes, or between quasi-quotes when not inside a $ or @ hole.

indent - The suggested indentation level for the next line, unless the next line begins with closer.

closer - The character that would close the most recent unclosed openner.

closeIndent - The suggested indentation level for the next line if it does begin (after trimming) with closer.
