I'm not sure if one is clearly superior to the other.  But having one,
there's not much motivation to add the other.  But `string-join' can
definitely be added to the new helpers.el.

These also would be good candidates for helpers.el.

I can't remember using something similar to string-chop.  In Perl, this
was handy because it's frequent to receive "a line with a terminating
LF", but in Emacs it doesn't seem to happen nearly as often.
