Prawn - Indent the first line from the begining of each paragraph

Question

Hi,

I would like to indent the first line of each paragraph. According to the following commit, it seems to be done.

http://github.com/sandal/prawn/commit/d58f7b4f93d9a5f9720afc00520303666b1c3327

But the main gem release is not yet updated. So even after:

sudo gem update

it's not okay, and I don't know how to update localy my Prawn gem. Can you help me?

Thanks
