Whats up with Bash expansion?

Expansion seems to work different and actually causes time consuming
delays in getting the text right.
Here is an example:
I use a few homeboy variables to help navigation. *$rea equals
/home/reader, so in these command:
* ls $rea/some<tab> to complete to /home/reader/someplace
That is how its worked for eons... but now when I hit tab the buck
gets escaped $rea/som<tab> and of course that cancels any expansion.
Pre ubuntu (for me) I would see both the variable and the partial
directory name expand when hitting <tab>.
So instead of $rea expanding to /home/reader.... it gets escaped
$rea. *Now I have to back up and remove the escape slash and have
lost the expansion property that has been such a time saver.
Does anyone know if this is something that is configurable?
At least on some versions of Ubuntu its broken, indeed. AFAIK, its not configurable, but would love to find out otherwise. Its a royal PITA.*
In /etc/bash_completion, look for the line ...*
**if shopt -q cdable_vars; then
and comment out that entire if section (5 lines). On 10.04 its at line 1385. On 8.04 (it predates that release), *its on line 3154. Then start a new shell, and see if that is better. This works for me.*
