Hi Karthik,

Thank you so much for the detailed review.

> Where is the 'uninitialized variable hazard'?

Hummm...seems that 'die_on_error ? NULL : &error_code' would just immediately 'die()' internally if NULL was passed. So there was no *real* hazard of uninitialized error_code being evaluated externally. Anyway, this change hardly qualifies as a major focus, and I will remove it from the commit message.

> I couldn't find a discussion, why did we merge the commits?

It was suggested by Junio, ensuring that every commit in the history remains strictly atomic and bisectable.

Show 5 quoted lines

Great catch. Will change in v11.

Thank you again for the guidance ;)
