[plugin-shell][FR] accept commands with arguments

[vp1981]

Hello.

If I understand the code of the 'shell' plugin (plugins/shell/src/lib.rs) correctly, it currently doesn't accept commands with arguments.

Is this correct?

Is it possible to extend the 'shell' plugin to use commands with arguments?

P.S. I would like to run texdoc as follows:

:sh texdoc minted

It's an issue with your shell wrapper as mentioned in #183 instead of an issue with the shell plugin.
