+            Adjust matched file list
+            If we pass a directory to commit whose only commitable files
+            are largefiles, the core commit code aborts before finding
+            the largefiles.
+            So we do the following:
+            For directories that only have largefiles as matches,
+            we explicitly add the largefiles to the matchlist and remove
+            the directory.
+            In other cases, we leave the match list unmodified.
