I am plugging for the gfortran MatterMost website. https://gfortran-mm.osuosl.org/main/channels/insights
At that location one can go to the top of the page and find all the hints one needs to use git including commits and correcting logs. I use it all the time to fix-up the git log or change author, etc.
If you do not have access to it, send me an email and I can send you an invite. It is all web browser based, however one can also use an app from your phone if you wish.
Regards, Jerry
