David,

well, hopefully it just needs a fix. i don't seem to have scanf. so i can't 
test this. i take it though that the problem is that there is a scanf 
directory and a scanf include file. the require is finding the directory 
first and thus failing. hmm...just need to make sure it looks for the file 
first, prior to trying it as a "directory-require". how to do?...

yes, there may be some unexpected "successful" requires due to this code that 
normally would fail, but (once fixed) i see no reason that it should cause 
previous code to break. so there should be no issue of quarantining.

also, that was an aside adjustment. the second part is the more intersesting 
of the two alterations. see any problems with that? i esspecially like this. 
i find it awfully painful to have to go through my files and change requires 
simple b/c i've decided to put them in a different directory.
