Finding EOF problems in files

[RICH at MIT-AI (Charles Rich)]

Is there (or could there be) a command to check for balanced parens.
It would be nice if there was a simple command to invoke on a file to find
the problem when a LOAD failed because of CLOSE token before EOF.
Unfortunately, simply doing C-U C-U C-U M-C-F doesn't work for two reasons:
	1. When the command fails to complete, it leaves the cursor where
	   it started, rather than where it failed.
	2. M-C-F doesn't cause an error on the form () ) () ; you have to
	   go backward from the end of the file with M-C-B to find this problem.
Thanks,
	Chuck.
