bug#11202: Acknowledgement (24.0.93; shell.el: Documentation for M-x shell sometimes shows wrong keybinding for describe-mode)

[David Röthlisberger]

Note that this problem manifests itself more often than the original report 
implies.

In the *Help* buffer for `shell', if I navigate to the help for any of the 
linked functions or variables, then click the `[back]' link, the help text for 
`shell' has changed to the incorrect text as per the original report.
