Re: Why (substring "abc" 0 4) does not return "abc" instead of an error?

Got it.  I'll sleep on this.

Now that the social pressure of nice Emacs fellows convinced me 
there was something wrong in my expectations, I still vote for
including `string-head' and `string-tail' (which see).

I see two reasons for not including them: one would be because
they are useless; the other because they would inevitably make 
someone request a new argument ERROR to throw an error when the
length of the head/tail is bigger than the string... but who
would be such a twisted mind?

Anyway, no more argument for tonight.
