Bug#918099: what is so special about TZ?

[積丹尼 Dan Jacobson]

Package: bash-completion
Version: 1:2.8-5

Why does
$ grep TZ a<TAB>
not expand?
$ grep TZa a<TAB>
Does.

Same problem with ls, whatever command.

No there is no file called TZ.

No other environment variable names don't trigger the problem.
