+       When running the command with `-u` and `-m` options, the
+       merge result may need to overwrite paths that are not
+       tracked in the current branch.  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.  This
+       option tells the command to read per-directory exclude
+       file (usually '.gitignore') and allows such an untracked
+       but explicitly ignored file to be overwritten.
