[Octave-patch-tracker] [patch #8139] cd: Add Bash-like "cd -" shortcut to change to last dir from input prompt.

[Mike Miller]

Update of patch #8139 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #1:

Is there a reason for only wanting to do this at the top execution level? In
the unix shell it is perfectly legal to do "cd -" inside of a script or a
subshell.

I agree it's probably unlikely that anyone names a directory "-", but it is
something to consider.

I like the idea, as long as no one else is worried about potentially breaking
compatibility with directories named "-".

I'd prefer something like "cd: no previous directory" as the error message.
