The beauty of definitions is that they can be anything you want.

I think most of us will agree with me that CVS must be able commit any
file given to it, and reproduce it exactly.  Arguing that it should commit
only the files it deems suitable is way off the mark.

I did.  Now tell me why there's a practical difference between what the code
does and what my grep does.

I reviewed the file_has_markers function in some detail.  It matches
exactly the same set of strings as the pattern I gave above.
