Refine the todo entry for install.html

Update the description of what needs doing. The splitting code exists, but
it's sub-optimal and not re-usable. Correct the name of the Makefile target -
it's 'install.html' with a period, not 'installhtml'.

 Challenges here are correctly identifying the groups of functions that go
 together, and making the right named external cross-links point to the right
-page. Things to be aware of are C<-X>, groups such as C<getpwnam> to
-C<endservent>, two or more C<=items> giving the different parameter lists, such

+page. Currently this works reasonably well in the general case, and correctly
+parses two or more C<=items> giving the different parameter lists for the
+same function, such used by C<substr>. However it fails completely where
+I<different> functions are listed as a sequence of C<=items> but share the
+same description. All the functions from C<getpwnam> to C<endprotoent> have
+individual stub pages, with only the page for C<endservent> holding the
+description common to all. Likewise C<q>, C<qq> and C<qw> have stub pages,
+instead of sharing the body of C<qx>.
+
+Note also the current code isn't ideal with the two forms of C<select>, mushing
+them both into one F<select.html> with the two descriptions run together.
+Fixing this may well be a special case.
