Ok... but I probably misunderstand a bit:
The default has not been q(save = "ask") but q(save = "default"),
and that default has depended on startup.
Even now, "R --no-save" already did have the desired effect,
on Unix at least. For my ESS setup, I have made this an automatic
default many months ago.
Wouldn't it be easier and sufficient to make "--no-save" a
working option on all platforms ?
Or is the point really about changing the quitting dialog?
For me quitting *without* a dialog is the most important thing
which I use (often several times a day).

People have asked me in private about this, and I didn't know
Is it true that this means that people can no longer commit the
"cheap package install trick" on Windows for R-code-only
1) install a source package on a Linux/Unix/MacOSX machine
(where it is often simple to have all the necessary tools available)
2) zip the resulting installed package
3) unzip it on the target Windows machine into the corresponding
Of course, this trick will not provide any *.chm help files.
Will the cheap-installed package still work, using the *.txt (or
*.html) help files?
