Not can skip but (in most cases) should skip.

OTOH: You should have replied to the OP. I know of that fact, that's why I said that it's equivalent to

('name1,', 'name2,', 'name3')
[download]

and not

('name1', 'name2', 'name3')
[download]

Update: Just a side note ;-) Careful with those apostrophes! Generally there is no such thing as a plural apostrophe in any language I know of english and german. So it should be "commas" not "comma's" ;-)

Update 2: Thanks to Perl Mouse I've learnd that the dutch language has a plural apostrophe in some cases. That's the reason for the correction above...
