Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When I use tcsh (which echoes command input) in a shell buffer, entering "M-x 
dirs" fails because it mistakens the echoed "dirs" string as the directory 
string to use as input when changing the buffers default directory.  The 
attached gziped patch file contains a fix.  The patch also binds the "dirs" 
command to "\e\C-m" in shell-mode-map (previously unbound) to make it easy to 
invoke.  Finally, a test has been added to see if "shell-dirstack-query" is
non-nil.  If so, it is not overwritten.

To enable the fix, the user must set comint-process-echoes to t.
