 * Print up to the first three command line parameters that follow the command
 * itself. Print them each on their own line, prefixed with their index
 * number.  Print the parameters only if they are actually there and each on
 * their own line.
 * Example input/output:
 * ./h4 a b
 * 1: a
 * 2: b
 *
 * ./h4 a b c d e f
 * 1: a
