Use of \iq in FRT

[cmahte]

Using the \i* paragraphs as "span collumn" paragraphs. This makes \pc used on title pages for add-on info impossible.

Need "introductory centered paragraph". Best found is that I locally have \iq (no number) set for intro font, centered text, and the iq#'s hanging indent, increasing margin offset.

However, \iq by default is not centered explicitly (although the example in the 2.4 manual displays it that way.)

Follow up best method.
