;; `pdf-tools-install' has a change to reinitialize them as
;; `pdf-view-mode' buffers. This is necessary because `pdf-tools-install'
;; won't do this to buffers that are already in pdf-view-mode for some
;; reason -- even though those are the buffers we need to reload!

;; HACK If pdf-tools was loaded by you opening a pdf file, once

;; Therefore, it is imperative that the window config is restored.
