About ten times a day I do something like this:
$ cd cd tedu
ksh: cd: bad substitution
What does that even mean? According to the source, but not the manual, there
is some two argument cd syntax which substitutes something. I have never once
tried to do this on purpose.
Thus, I think the error message should be changed to be more appropriate.
Those few power users who try to substitute paths can probably deal with the
error message better than I can.
