  Prefer https: URLs
  
  In Gnulib, Emacs, etc. we are changing ftp: and http: URLs to use
  https:, to discourage man-in-the-middle attacks when downloading
  software. The attached patch propagates these changes upstream to
  Automake.  This patch does not affect files that Automake is
  downstream of, which I'll patch separately.
  
  Althouth the resources are not secret, plain HTTP is vulnerable to
  malicious routers that tamper with responses from GNU servers,
  and this sort of thing is all too common when people in some other
  countries browse US-based websites. See, for example:
  
  Aceto G, Botta A, Pescapé A, Awan MF, Ahmad T, Qaisar
  S. Analyzing internet censorship in Pakistan. RTSI
  2016. https://dx.doi.org/10.1109/RTSI.2016.7740626
  
  HTTPS is not a complete solution here, but it can be a significant
  help. The GNU project regularly serves up code to users, so we should
  take some care here.
