doc-view-new-window-function seems to be run from a
window-configuration-change-hook, right? If so, why do you expect it
to be run only once, or not run when you type "M-x TAB"? E.g., the
latter pops up the completion buffer and/or splits the window, which
constitutes a change in window configuration:
-- Variable: window-configuration-change-hook
A normal hook that is run every time you change the window
configuration of an existing frame. This includes splitting or
deleting windows, changing the sizes of windows, or displaying a
different buffer in a window. ^^^^^^^^^^^^^^^
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I think a function written to run off that hook should be defensive
and not assume anything about when it will or won't be called, or how
many times. Just grep the C sources for
run_window_configuration_change_hook, and you will see why.
