Three spaces after a period? That's a lot of space.

Inflation, don't you know.

'may' or 'must'?

After reviewing the implementation, I understand that this function decides,
based on the installer and installation state, whether to add, remove, or leave
unmodified the product commands. I think the comment here could better reflect
that fact.

Even when reading the call sites, the name is a bit confusing. Ideally, the name
would be something that said
"AddWorkItemsToAddOrRemoveQuickEnableProductCommand" but that's a bit long :(

[grt (UTC plus 2), 2011/03/02 19:48:28]

Nothing will break if they aren't NULL on uninstall, so I wouldn't say must. 
I've updated the comment to make it clear that they're not used on uninstall.
Done.
