The creator code is obsolete and doesn’t serve much of a purpose, as we already mention TextMate in the service name.
When updating a keychain item we leave out kSecAttrLabel and kSecAttrComment, which may fix issue #1029.
The new (non-deprecated) API no longer allows us to target a specific keychain for add, remove, and lookup.
This wasn’t used by TextMate itself but was extremely useful for writing tests against the API (using temporary keychains).
There is currently no way to add a TextMate (1.x) license to the key chain, but those who used TextMate r9147 or earlier should have one stored already.
