  Modified files:
    lib/libarchive       archive_write_set_format_pax.c 
  Log:
  Certain filenames between 245 and 255 characters long would cause an
  internal error if pax extended attributes were being generated.  Being
  < 255 characters, the first-pass path editing (to generate a
  ustar-compatible name for the main entry) wouldn't occur, and the
  second-pass path editing (to generate a ustar name for the pax
  attributes entry) assumed the input was already < 245 chars.
  
  The core problem here was using an abbreviated algorithm for the
  second pass that relied on the first pass having already run.  The
  rewritten code is much simpler: It just uses the full path-shortening
  algorithm for building both ustar pathnames.  This way, the second
  ustar pathname will always be short enough.
