Coding is never simple and I appreciate your work.
But is the 10 years old reason still relevant?

I don't know when the hook system was implemented, but I didn't expect=20
that the data from the backends would be altered before it reaches the=20
hook, which is designed for doing such operations.
It took me quite some time find this, because I first thought there is a =

problem with my hook or the original data from the backend.

At least I think this trim function should be mentioned in the hooks=20
documentation, so that it is clear, that the data arriving at the hook=20
might already be trimmed.
