New Revision: 357125
URL: https://svnweb.freebsd.org/changeset/base/357125

Log:
  Import libxo-1.4.0:
  
      - Two changes to encoder options:
          encoder options may use plus or colon, but only one
          encoder names can be specified as "@name"
          This results in the syntax:
  
          df --libxo @csv:no-header:leafs=name.available-blocks /
  
      - If xo_set_program is called before xo_parse_args, honor the requested value
      - add xo_errorn* function; repair newline-adding-on-xo_error bug
      - test programs now use fixed name, since linux libtool prefixs "lt-"
      - Fix "horse butt" comment in source code
      - update test cases
