Open shell and run command

[sebdah]

I'm looking to support Vim for https://github.com/sebdah/vim-delve. It currently only supports Neovim, because of the use of the :terminal feature in Neovim.

I'd need to call vim-shell and have it run a command (not in the background). See what I'm doing for Neovim here https://github.com/sebdah/vim-delve/blob/master/plugin/delve.vim#L201. I couldn't find a way to do that in vim-shell, am I missing something or is it not yet supported?
