history-delete-duplicates and read-file-name

[Piet van Oostrum]

The variable history-delete-duplicates, when non-nil, is supposed to
suppress duplicates in minibuffer reads with history. However, there is one
occasion where it fails:

Calling read-file-name with a default that is somewhere in the
file-name-history but not the most recent entry, and selecting the default,
causes read-file-name to add the selected filename, without removing the
existing entry. This is because it adds the new entry after read_minibuf
has finished. It should also check history-delete-duplicates.
