Side note to the side note.

A related naming guideline I failed to follow (because I was
mostly copying your code) suggests that the hash here should be
named %fullname, instead of %basename.  Then logically:

	$fullname{'hello.c'} = 'a/b/hello.c';

that is, you consult %fullname hash using the basename as the
key to extract the corresponding fullname.  The naming guideline
is "Name the dictionary after its values, not after its keys."
