[PATCH] Fix extraous comma in printf

[Michael Chang]

This patch is to get intended output from printf shell command, as the
comma is not used as separator for it's arguments, they will eventually
be outputted together with the variables.

Though it does not affect or break any function currently, I'd like to
address this hidden problem and hope to get some attention of it.

Thanks.
