commented-out parentheses cause error in C-c C-c

[Levi Waldron-4]

For example the following R code, which contains no errors or unbalanced
parentheses:

## fun <- function(x){
##   x^2
## }

print("hello world")

Using this with an inferior R process, all of the eval commands work except
for C-c C-c.  If I hold the cursor over the print line (or anywhere) and
press C-c C-c, I get the following error and it does not evaluate:

Scan error: "Unbalanced parentheses", 22, 60

I am using GNU Emacs 21.4.1, ESS version 5.5.  The same problem existed in
ESS 5.3.8.

Thanks, I can confirm this on Emacs 23.1 (no fix yet though).
