defaults in join doc

[Karl Berry]

I ran across some notes from 10 or so years ago reminding me that the
list of defaults in the join documentation might be more readable as an
itemized list.  Better late than never, maybe.  Here's a diff:

  @end example
  
! The defaults are: the join field is the first field in each line;
! fields in the input are separated by one or more blanks, with leading
! blanks on the line ignored; fields in the output are separated by a
! space; each output line consists of the join field, the remaining
  fields from @var{file1}, then the remaining fields from @var{file2}.
  
  The program accepts the following options.  Also see @ref{Common options}.
