Re: [RFC PATCH 0/1] Add lines to `git log --graph` to separate connected regions

>> This leads to a problem. Say there are two connected regions, each having two

>>
>> * a2
>> * a1
>> * b2
>> * b1
>>
>> which may lead to a misunderstanding that these four commits belong to the same

>>
>> * a2
>> * a1
>> ---
>> * b2
>> * b1
