The installer is built with Inno Setup (see www.innosetup.com).  I just
tried the lines above, and I see that some of the defaults are changed,
but not all.  The "startup options" do not get saved in the file.
These
are not standard Inno Setup settings, we customized them for R.

You can avoid the dialogs by using /SILENT or /VERYSILENT command line
options.

I've asked on the Inno Setup newsgroup whether there is support for
saving custom options in the INF file.  If so, I'll try to fix this for
2.8.0.
