My first reaction to this would be "Why?" -- under what circumstances
would you want to obscure the fact that the script is changing
directories? -- but to return to the direct question ...

The SHINSTDIN test has been part of autocd farther back than any
changelog or source control can resolve, so it's probably related to
cd printing out the name of the new directory whenever an autocd takes
place, and the assumption is that this would not be wanted when the
input is from a script file (but simply changing silently would also
be bad).

This probably should be documented somehow.  Suggested wording, anyone?
