If a file contains N open parens and N+1 closing parens, Emacs displays an 
error message pointing to the closing paren to which no opening paren 
corresponds.

If a file contains N+1 open parens and N closing parens, Emacs displays an 
"End of file during parsing" error message.  It could be a bit smarter, 
though: if one assumes that the file is properly indented, which is 
usually the case, whenever a parenthesis is read in column 1, the number 
of opening and closing parens must match.  IOW, Emacs could point to the 
first such place where this is not the case.  Such a hint would not be 
100% accurate, but would be helpful.
