 Values can be omitted, in which case the key/value delimiter may also be left
 out.  Values can also span multiple lines, as long as they are indented deeper
 than the first line of the value.  Depending on the parser's mode, blank lines
 may be treated as parts of multiline values or ignored.
 
 Configuration files may include comments, prefixed by specific characters (``#``
-and ``;`` by default [customizable]_).  Comments may appear on their own in an
-otherwise empty line, or may be entered in lines holding values or section
-names.  In the latter case, they need to be preceded by a whitespace character
