 sql rest_of_line

 treats rest_of_line a a sql command (non-select) and
 executes it.

 note: we should modify this to allow multi-line.
 in order to do this, we should simply keep prompting until
 we get a line that ends in a semi-colon, which we will strip
 off.  This should be captured in a separate routine, which we
 can use for a number of other commands (explain plan, select, etc).
