svn commit: r334636 - head/usr.bin/indent

Author: pstef

New Revision: 334636

Log:
  indent(1): add --version option
  
  There exist multi-platform programs that check indent's version in order to
  know what they can expect from it. GNU indent provides that via --version,
  so implement the same option here.
