Hi, I am not sure if this is a bug but it was surprising to me so I thought I'd report it here. I added `ui.column=auto` to my gitconfig and that does not work so well with pipes so I want to use `--no-column` option. I was a bit surprised that this does not work? It seems that `--merged` picks up `--no-column` as a commit reference instead it being parsed as an option. hholst@fb-hholst3 ~/src/a3c-batch (feature/NetworkHandler) [conda:tensorflow] $ git branch --no-column --merged * feature/NetworkHandler [snip] hholst@fb-hholst3 ~/src/a3c-batch (feature/NetworkHandler) [conda:tensorflow] $ git branch --merged --no-column fatal: malformed object name --no-column hholst@fb-hholst3 ~/src/a3c-batch (feature/NetworkHandler) [conda:tensorflow] $ git --version git version 2.13.0 Best, Henrik Holst (Not on the list)
