Documentation

Non-nil means buffers visiting files read-only do so in view mode.

In fact, this means that all read-only buffers normally have View mode enabled, including buffers that are read-only because you visit a file you cannot alter, and buffers you make read-only using C-x C-q (read-only-mode).

Probably introduced at or before Emacs version 20.1.
