I used b4 command to prepare and send the cover letter and patch for v2, 
not sure what happened.

I see that other people's patches have a [PATCH 0/n] email as a start 
that describes their patch series, this is called a cover-letter in b4 
and git-send-email right?

This is because rustc-bindgen-libclang-version can't find the bindgen 
and returns nothing. Sorry I forgot to mention this, it's another reason 
why I wanted to separate the script, in a separate script we can easily 
fallback to return 0 when an error is encountered.

Adding a second line `default 0` doesn't work, I'll try to fix it. BTW, 
when I fix it, if the diff isn't too large, do I need to open a v3 
patch, or simply replying to the thread just fine?
