Compabiltiy with oh-my-git

[metiulekm]

oh-my-git is extremely great and has support for custom prompts using $omg_ungit_prompt and $omg_second_line. I quickly tried to make it talk with promptline.vim, but, unless I'm missing something, it failed beacuse generated file overwrites $PROMPT and $RPROMPT every time it displays a prompt. Any ideas on how can I use it in this way? 😃 (I am using zsh)
