Although I don't see an explanation in the user documentation on this
subject<http://ridiculousfish.com/shell/user_doc/html/index.html#completion>,
what I have found in general (and this may be different specifically for
the `cd` command) is that pushing <TAB> once will either:
- complete out to the longest common filename, or other completion
- e.g. $ ls /bin/mou<TAB> will complete to $ ls /bin/mount
- or if it's already at the longest common completion it will give you a
list of possible completions
- e.g. $ ls /bin/mount<TAB> will show
- …bin/mount …bin/mountpoint
- Then hitting tab repeatedly after this will cycle through the
possibilities that were given in the previous list of possible completions
(so if the first one is right you just hit TAB again and keep on moving)
I think this behavior might be somewhat similar to what you're seeing. The
double TAB habit from bash can be broken.

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
