You're right, Nikolay. -u NONE is not disabling the autoload feature.

What I've found is that -u NONE, among other things, sets
'compatible', which precludes pathogen from defining its functions.
Near the beginning of pathogen.vim is this stanza:

if exists("g:loaded_pathogen") || &cp
finish
endif
let g:loaded_pathogen = 1

This is why pathogen#infect() isn't recognized: its definition was
never seen by Vim.

Hashjie, in order to use pathogen.vim along with -u NONE, you must
take several manual steps after Vim has loaded. I've found that this
sequence works with my setup:

$ vim -u NONE
:set nocompatible loadplugins
:so ~/.vim/autoload/pathogen.vim
:call pathogen#infect()
:runtime! plugin/*.vim

Then you can see with :scriptnames that your plugins under .vim/bundle
are loaded. However, when I do this I get several warnings and errors.

I'm sure that you have your reasons to combine -u NONE with Pathogen,
but it seems like a lot of extra work to me!
