This is the default bash-4.2 behavior. There has been some controversy
surrounding the behavior change. Take a look at
http://lists.gnu.org/archive/html/bug-bash/2011-09/msg00007.html
for a brief discussion of the issues and a patch that adds several things
to make completion work more flexibly in the face of shell variable
expansion. A version of that patch will appear in bash-4.3.
