    Introduce line-up-first and line-up-last macros · 2e399427

    This patch introduces the line-up-first and line-up-last macros in
    control-flow.  The macros have been popularized by Clojure and afterwards
    adopted in Emacs Lisp (see thread-first and thread-last in subr-x.el).
    This implementation is a port of the latter, where we use a common
    line-up-iter(ative) tail recursive function for computing the results.  The
    choice of the full name was made in the spirit of the library, conservatively
    avoiding new syntax like -> or ->>.
