One of the things I hate about merge-based Git workflows is git makes a default Merge 123234234 from user/dave/fsdf
message which:
a) Is shit - it contains zero useful information (what's in the change??) and contains information you explicitly don't care about (the temporary branch name the author happened to use). a) Makes people think they are supposed to use that message.
It would probably be better if the default message was blank. But also squash & rebase is generally better anyway and it avoids this problem entirely.
Dunno why you're being downvoted. It's very obviously deliberately chosen to make 12 year olds giggle.
