What is this supposed to look like in the kind of index formatting
that texinfo.tex uses, with the dot leaders?  Should the leaders be
present or not for a "see"?  (I guess not.)   Where does a "see also"
appear in relation to the leaders and the other page numbers?  (I guess
after all the page numbers, after the leaders.)  What precedent is
there for this?  It is much more common for there to be no leaders
when an index is formatted and for the page numbers to follow the
index entry immediately.  I tried to check if similar output could
be output for LaTeX, but I didn't find how to get the dot leaders type
of index formatting in the time I spent on it.
