to me privately, but I allow myself to reply CC'ing  ESS-help,
since I think the answer should be more widely available

could it be that it is completely harmless?
just showing the last message which happens to be "Fontifying" ?

(I meant to say that this has been *discussed*, not implemented)

You can add "--save" to the default R arguments, 
    M-x customize-variable <Enter> inferior-R-args

but this doesn't help against *killing*  the *R* buffer. 
It will just automatically save upon  q()  [or C-c C-q hopefully].

BTW: I never save a workspace or work with .RData: 
     When you work with ESS, it's typically very reasonable that
     everything important is recreatable from the corresponding
     *.R source file. 
     The few times I create "expensive" objects, I save() them
     explicitly (but to "<myobject>.rda", not ".Rdata") and can 
     load() or attach() them later.
     Still all these save(), load(), .. commands are part of my
     *.R script file.

Thank you,
and also from me
      "Happy New Year!" 
to all ESS users and your loved ones.
