Thanks.  It seems your fix doesn't work.  The reason is that
`after-find-file' calls `view-mode-enter' *after* calling
`doc-view-mode' via `normal-mode'.

However, adding the following line to the end of `doc-view-mode'
seems to work (because `after-find-file' checks for `view-read-only'
before calling `view-mode-enter'):

    (set (make-local-variable 'view-read-only) nil)
