The command usually - refuses to proceed with the merge to avoid losing such a - path. However this safety valve sometimes gets in the - way. For example, it often happens that the other - branch added a file that used to be a generated file in - your branch, and the safety valve triggers when you try - to switch to that branch after you ran `make` but before - running `make clean` to remove the generated file.
