So far, something like

 @findex \relative

possibly followed by

 @syncodeindex fn cp

should do it.

This part I don't understand.  Do you mean that the sorted index
should have "\relative" among index entries that start with `r',
instead of those that start with `\'?  If so, I don't think you can do
this, except by a trick, something like

 @cindex relative mode, the @code{\relative} command

Each index is sorted using 1 of 2 possible comparison functions:
either mbscasecmp (the default) or strcoll (if the configure test for
that function succeeds).  Does this answer your question?
