Subject: fix printing out help message (list of command line options) (tiny change)
X-Git-Tag: v4.4.1.20091019~49

fix printing out help message (list of command line options) (tiny change)

The postfix increment always resulted in an attempt to print out an
option on the right side regardless of one actually existing. Use
prefix increment to prevent a crash when printing an odd number of
options.
