It won't work: you forgot to quote /path/to/extra.vim

I personally would have written that either as
vim --cmd 'leg g:extrasource="/path/to/extra.vim"'
or, if I know that I will use this too often:

function vim-so()
{
emulate -LR zsh
vim --cmd "let g:extrasource=${(qqq)1}" ${@[2,-1]}
}
. This is safe because (qqq) will enclose argument into double quotes with
proper C escaping which is accepted by vim.
