In principle, I am not opposed to the idea of making read-tree
take the ignore information into consideration.

But I would suggest you to be _extremely_ careful if you want to
try this.  I do not have an example offhand, but I would not be
surprised at all if there is a valid use case where it is useful
to have a pattern that matches a tracked file in .gitignore
file.
