pager support for Go

 This package contains easy $PAGER support for Go (i.e. less(1), more(1))
 with sane defaults.
 .
 By default pager uses less(1) with the args: -X -F -R --buffers=65535
 and sets LESSSECURE=1 before starting less(1).
 .
 If less(1) is unavailable, pager falls back to more(1).
 .
 The PAGER environment variable is honored.
