dd: adjust --help output so help2man formats the man page properly

[Jim Meyering]

FYI, without the change below, the dd man page entries for
"directory" and all following flags were mangled:

       direct use direct I/O for data

              directory fail unless a directory dsync     use synchronized I/O
              for data sync      likewise, but also for metadata nonblock  use
              non-blocking I/O noatime   do  not  update  access  time  noctty
              do  not  assign  controlling terminal from file nofollow  do not
              follow symlinks

       Sending a USR1 signal to a running `dd'  process  makes  it  print  I/O
       statistics to standard error and then resume copying.

Now, its rendered like this:

       direct use direct I/O for data

       directory
              fail unless a directory

       dsync  use synchronized I/O for data

       sync   likewise, but also for metadata

       nonblock
              use non-blocking I/O

       noatime
              do not update access time

       noctty do not assign controlling terminal from file

       nofollow
              do not follow symlinks

       Sending a USR1 signal to a running `dd'  process  makes  it  print  I/O
       statistics to standard error and then resume copying.

Subject: [PATCH] dd: adjust --help output so help2man formats the man page 
properly

* src/dd.c (usage): Use two spaces (not one) to separate
"directory" from its description, so help2man formats
the derived man page properly.
