Selectively enabling VIM plugins with Pathogen + Localvimrc
===

I'm working on different projects and I want to select what plugins to enable (or disable) for every project. I'm using Pathogen to manage my plugins. 

Plugins list:

    .vim \
         |-bundle \
                  |-vim-markdown
                  |-latexsuite
                  |-dirdo
                  |-localvimrc
                  |-nerdtree
         |-autostart
         |-doc


I've a main `.vimrc` which by default enables all plugins and a local `lvimrc` in every project main directory enabled by [Localvimrc](https://github.com/embear/vim-localvimrc), in which I add some plugins to the disabled plugins list.

### `.vimrc`

    " Enables vim-pathogen and disables nearly all plugins
    call pathogen#runtime_append_all_bundles()
    call pathogen#helptags()
    let g:pathogen_disabled = []
    " This makes vim invoke Latex-Suite when you open a tex file.
    filetype plugin on

### latex-project's `lvimrc`

    let g:pathogen_disabled = []
    call add(g:pathogen_disabled, 'vim-markdown')

### blog project's `lvimrc`

    let g:pathogen_disabled = []
    call add(g:pathogen_disabled, 'latexsuite')

## The problem
Everything works fine except [vim-markdown](https://github.com/tpope/vim-markdown) which is not loaded when I open my blog's html/markdown files (I've already added *.html extension in  `ftdetect/markdown.vim`). Moreover, `vim-markdown` is not listed in the output of `:scriptnames` when editing my blog files.

Any hint?
