CR fix for create_help.pl

The attached tiny patch removes spurious carriage returns that might be
copied by the script that generates psql's help. (You can get the
spurious CRs if you use a CVS client on Windows that does line end
translation.)  Elsewhere, the patch should be totally benign.

This removes quite a number of the compile warnings I posted the other day.

cheers
