[Libreoffice-qa] Correct use of bibisect to identify a particular commit

[Alex Kempshall]

Hi Xisco

Still don't understand what the  technique is to get from a bibisect log 
to a bisect log.

If you remember I identified, by using bibisect, when a regression 
occurred. Then you went on to identify the actual commit see

https://bugs.documentfoundation.org/show_bug.cgi?id=118220#c3

Just want to know how you got from my bibisect.
