 This causes the command to ignore differences in file modes recorded
 in the index and the file mode on the filesystem if they differ only on
 executable bit.   On such an unfortunate filesystem, you may
 need to use `git-update-index --chmod=`.
 
+Quite similarly, if `core.symlinks` configuration variable is set
