This request is slightly confusing. The first sentence implies that you want offset to be a requirement (as opposed to being an option). That would not be acceptable. Later it seems that you want it added as an option (as opposed to not available). That seems sensible, and indeed, in 3.1, offset *is* an option (with a default of 0). So I am closing this as out-of-date (because fixed).

For future submissions, upload patches to the tracker as a file attached to the issue. The url you gave now gives 404 not found error.
