I cannot tell about the github specifics, however, when in doubt 
about the state of my branches, I run a variant of `git log -8 
--graph --pretty=format:'%h - %d %s <%an>'` which will display a 
textual representation of the git graph with heads and tags 
annotated to the listed commits.

For many years, this has helped me to quickly figure out what was 
going wrong with my branches.

On the dmd repositories, taking the last 20 entries :
