A question about the psql \copy command

Through the work on the patch [1], I had a question about the psql \copy
command. We are permitted 1) but not permitted 2):
1) \copy foo from stdin ;
2) \copy foo from stdin;
Is this intentional? I think it would be better to allow for 2). Attached is a
patch.

Thanks,

Best regards,
Etsuro Fujita
