Indeed: filetype detection is turned on by the vimrc_example.vim, but
it is neither the 'compatible' nor the 'nocompatible' default in the
absence of startup scripts (i.e. neither "vim -u NONE" nor "vim -u
NONE -N" have it. Even "vim -u NORC -N" i.e., no vimrc but with global
plugins and 'nocompatible' doesn't set it.)

To get a reproducible setup with filetype detection, you might want to
do something like

vim -u /usr/local/share/vim/vim74/vimrc_example.vim

(no need to use -N in this case because the vimrc_example.vim sets it.)


Best regards,
Tony.
