Mermaid cli not working for subgraphs

[furstenheim]

Very nice project.
I'm trying to use the mermaid cli for a subgraph but I cannot manage to get it to work

 graph TB;
    subgraph B;
    C --> D;
    C --> E;
    end;

Without the semicolons it works in the live editor

I've managed to create a simple graph with the cli, so it is correctly installed

The solution/problem is found under issue #231 -- it doesn't like tab characters. Use spaces instead of tabs or just align everything left and it works.

Please don't end each line with a semicolon. Semicolon is the old syntax which might not work any more.

The following works in both live editor and cliP:

graph TB
    subgraph B
        C --> D
        C --> E
    end

By the way, here is the new cli project: https://github.com/mermaidjs/mermaid.cli
