Is direxpand available yet (to fix dirspell)?

[John Caruso]

In bash 4.1, if you do "shopt +s dirspell" and type "ls /ect/passwd<TAB>"
it's corrected to "ls /etc/passwd".  In bash 4.2 with dirspell enabled,
the correction doesn't happen.

Some searching shows that the bash 4.1 behavior can apparently be enabled
again in bash 4.2 with a patch that adds a new "direxpand" option.  Is this
the case?  If so, is direxpand actually available in any released version
of bash yet (and if so which version)?
