New Revision: 287334
URL: https://svnweb.freebsd.org/changeset/base/287334

Log:
  MFC r272282,r272363,r272383:
  
    r272282:
      Search for the nearest PORTSDIR where Mk/bsd.ports.mk exists, from .CURDIR.
      This will only take effect if PORTSDIR is not set, as previously supported.
  
    r272363:
      Always resolve PORTSDIR to absolute paths using realpath(1).
  
    r272383:
      Revise r272363 by collapsing the tests into a for loop.
  
  Relnotes:	yes
