It does happen, but only if you install a package to the .Library directory.
That file is only intended as a listing of the main library, not other
libraries (as which are in the library path is session-specific). As NEWS
for R 2.6.0 says
o install.packages() on a Unix-alike now updates
doc/html/packages.html only if packages are installed to
.Library (by that exact name).
So I found this function make.packages.html, which seems to do what I
think should be done automatically. But it puts its output in a file in
/tmp/...,
It is a helper for help.start(), which sets up details of the current
packages in the session temporary directory. Please do consult its help
file.
The function used to update doc/html/packages.html is
utils:::link.html.help(), which is a wrapper for tools:::unix.packages.html.
which I then have to move, in an extra step, to where it should be. I
don't understand why this happens. I think that the old behavior was
better.
It caused a lot of needless updating.
I have two reasons for this. First, my R page (finzi.psych.upenn.edu)
has a list of all packages. As it happens, since this change has
occurred, it has been out of date, until today. Second, for my own
use, I have a Firefox bookmark to
file:/usr/lib/R/doc/html/packages.html, which was also out of date.
Let's hope you have a vaiid file:// URL ....

What we don't know is where you are installing your packages. If it is to
the main library, the behaviour should be unchanged (and I have just tested
it and it works for me). If it is to another library, the intention never
was to list packages in other libraries.
[Note that all this applies to Unix-alikes: Windows does not have symbolic
links (OK, some filesystems on some versions have a very limited form) and R
does things differently there.]
