I messed around with this option a bit.  what i've discovered is that
1) is doesnt accept extended regexps
2) it does allow the option to appear more than once, or at least twice
3) http://www.delorie.com/gnu/docs/cvs/cvs_130.html implies that it will
   only work for changes that affect one line.  ie:
	--ignore-matching-lines='foo'
   will not filter a diff like:
	> interface foo
	>  description foo to spamalot
4) it does not appear to appear to work with -U

YFMV (your frustration may vary).
