count should not accept any flags, not even -h

[krader1961]

I was pondering why prevd and nextd had separate blocks for detecting the --help flag rather than doing so in the main flag parsing loop. Then I realized it's because if you do prevd -h it would do count -h which won't return 1-- it will return the help for the count command. That is surprising to say the least. The count command is special. It should always return the number of arguments handed to it even if those args include -h and --. No arg should be special as far as count is concerned.
