The library doesn't remove the initial spaces

[cesards]

Hi!!

First of all, great work!

I realised that the library doesn't print spans correctly if there are spaces after line breaks. If you work with a rich editor nowadays, it removes the spaces and formats the code. Should this library contain this behaviour? I don't know if it's a bug or a feature.

Thanks.

For exampole, if we write:

1. This is one
 2. This is two
 3. This is three.

It won't print something like:

Thank you! I forget considering that situation. I will fix recently.
