Description

DumpCommand option for -c is specified as hasArgs() for unlimited
number of arguments following -c. The very description of the option
shows the real intent of using hasArg() such that multiple columns
can be specified as '-c c1 -c c2 ...'. Otherwise, the input path
is parsed as an argument for -c instead of the command itself.
