Hi, Emacs Developers!

Can you please add version> and version>= ?

  (defun version> (v1 v2) (version< v2 v1))
  (defun version>= (v1 v2) (version<= v2 v1))

I prefer

  (version>= emacs-version "26.1")

over

  (version<= "26.1" emacs-version)

Image that we provide < but without >. It would be painful.

That would indeed be painful, but for these very specialised comparison
functions, I'm not sure it's worth it to add (and document) them.  So
I'm closing this bug report; if somebody disagrees, feel free to reopen.
