OK. To be more clear, some detailed explanations are required in the
commit log. Please try to be very descriptive.
You can think comments like this:
- if comments are absolutely needed to understand the code, you should
put comments in the code (or write the code differently)
- if some feature context can help for the review, you should explain
context and design in the commit log
