They are provided so that "make test", "make emacs" and similar
Makefile rules can always load them. When elusive bugs are
encountered, it's convenient to be able to start a fresh instance of
Emacs which doesn't load the user's settings at all.

On the other hand, when the user's settings /are/ loaded, these files
should not be. Commit 586bbdb places them in a subdirectory lib/,
which shields them from the `load-path' since Emacs does not add
directories recursively.[1]

[1] Although one can force it to by calling
`normal-top-level-add-subdirs-to-load-path'. In that case,
remove "~/.emacs.d/evil/lib" from `load-path' afterwards.
