Hi,
This is how to reproduce the bug:
```
git checkout [tab-tab]
echo $x # outputs the name of the last branch on completion list
```
Or more directly:
```
__gitcompappend "something"
echo $x # outputs 'something'
```
No big deal, but it's annoying to know that `$x` is lurking.
Cheers,
Márcio Almada.
