+Three such highlight column markers are provided by default.  This is
+especially useful for languages like COBOL or Fortran where certain columns
+have special meaning.  It is also handy for aligning text across long vertical
+distances.  Multi-column characters, such as @kbd{TAB} are treated
+correctly.")
