I'd just like to say that I think this is a ridiculous user
expectation.  To take a binary named foo, rename it to bar, and expect
it to act as bar seems the height of taking advantage of accidental
implementation behavior.  (Except in cases where it's documented, like
rlogin, although I think of that as an irritating historical mistake.)

On the flip side, the original commit message said:

> egrep, fgrep were links This is in violation of GNU standards:

This seems like a very strange justification for a commit.  We don't
usually make a point of adhering to GNU standards.
