I tried to tab-complete the following:

make -C ~/src/linux/ M=$HOME/src/c[tab]

The shell completed $HOME/src/c to the path starting with 'c' that I
expected, but also incorrectly changed $HOME to \$HOME.

What is the status of this bug?

I recently upgraded to wheezy and have been plagued by this severe bug.
You either can't use variables when completing, or you have to remove
the backslash every time you complete (which is normally several times).
Very annoying!

Since this was posted in January, I was hoping a patch would be
available by now.

Thanks!
