Using the `:advertised-binding' property just implemented by Stefan is
a nice solution.  But other changes in `where-is-internal' broke preferred
key bindings in docstrings.  For example, compare the old and new
output of `C-h f Info-mode RET':

- h     Invoke the Info tutorial.
+ M-x Info-help Invoke the Info tutorial.

- u     Move "up" from this node.
+ ^     Move "up" from this node.

- t     Go to the Top node of this file.
+ <     Go to the Top node of this file.

- b     Go to beginning of node.
+ .     Go to beginning of node.

- w     Put name of current Info node in the kill ring.
+ c     Put name of current Info node in the kill ring.

Should we put `:advertised-binding' for all old preferred key bindings
explicitly?
