+       When running the command with `-u` and `-m` options, the
+       merge result may need to overwrite paths that are not

+       refuses to proceed with the merge to avoid losing such a
+       path.  However this safety valve sometimes gets in the

+       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.  This
+       option tells the command to read per-directory exclude
