<dd><p>Paint all pieces of text whose start matches extended regular expression
&quot;fromrx&quot; and whose end matches extended regular expression &quot;torx&quot; with
the given foreground and background colors, at least one of
which must be specified.  This means that, after an initial instance of
&quot;fromrx&quot;, all text until the first instance of &quot;torx&quot; will be colored.
This allows syntax highlighting to span multiple lines.
