<para>Now you realize that this is not nice code, and decide that you
want to use the <constant>const</constant> keyword for all

operator in front of the argument name. You would also like to
simplify the white space, so that there is only 1 whitespace character

white space (<literal>\s+</literal>) followed by one or more
alphabetic characters (<literal>\w+</literal>) followed by some more
whitespace (<literal>\s+</literal>) followed by an ampersand, and in
the process saved the alphabetic chunk and the ampersand for reuse in
the replace operation. Then we replaced the matching part of our line
with one whitespace followed by <quote>const</quote> followed by one
whitespace followed by our saved alphabetical chunk
(<literal>\1</literal>) followed by one whitespace followed by our
saved ampersand (<literal>\2</literal>)</para>
