Bug: global bash variable leak on __gitcompappend

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.
