I can see the difference of sizes in 
http://lilypond.org/doc/v2.0/input/regression/out-www/collated-files.html#accidental-cautionary.ly
But when I compile the example with lilypond 2.1.25 there is no 
difference. The parentheses are rendered correctly, but the third note has
a sharp the same size than normal.

Maybe it has it something to do with convert-ly?
this is the line actually compiled
\override Staff.Accidental   #'cautionary-style = #'smaller
I dont think so because
\override Staff.Accidental   #'cautionary-style = #'parentheses
works fine.

By the way, I think that I have discovered an undocumented feature:
putting two interrogation marks after a note, makes the alteration 
invisible:
cis??  no sharp rendered
cis??? rendered
cis???? not rendered
....
the same with the admiration marks !!
(I cannot test here if the accidental goes to the MIDI file or not)
