last entry skipped if not called from empty buffer

[Grueslayer]

The plugin found at https://github.com/gikmx/vim-ctrlposession misses the last session.

The plugin only lists files contained in a specific directory and returns that by ctrlp#obsession#init()

function! ctrlp#obsession#init()
    let flist = glob(fnamemodify(g:prosession_dir, ':p').'*.vim', 0, 1)
    let flist = map(flist, "fnamemodify(v:val, ':t:r')")
    let flist = map(flist, "substitute(v:val, '%', '/', 'g')")
    return flist
endfunction

This runs fine if called from an empty buffer. If you already loaded a file and start the ex-command from it, you get all files listed except the very last one.

This seems a bug in CtrlP itself.
