Just in case others have this problem:

M-x describe-variable RET comint-input-ring-size RET will show the
variable's current value.  The documentation string is missing a * at
the beginning of the first line, so it cannot be set with M-x
set-variable.  (Compare with the variable comint-buffer-maximum-size
which does have the magic star.)  This is an Emacs convention, not
specific to ESS.  Any suggestions for what we can add to the manual to
explain this?
