Fix a bug in the "cvs init" command. It ignored the global "-H" option.

I.e., "cvs -H init" went ahead and initialized the repository, and did
not print out a usage message.  Not nice.

Also added the "init" command to the list that comes out when you type
"cvs --help-commands".  There is still not a word about it in the manual
page.

Yes, I am sending these fixes to the FSF.
