Set values on WIN_OPEN rather than FILE_OPEN

This prepares the editorconfig plugin for upcoming changes in
vis version 0.9. See the following two commits:

https://github.com/martanne/vis/commit/450dc2df6a3b6443e372dc86cbefc8fede71b54d
https://github.com/martanne/vis/commit/de315f878fba5b6abf2810a05995ae1f5b00d45d

Thanks to Florian Fischer for bringing the issue to my attention.
