Fixes issues in symfony bash completions having side-effects for other completions. See composer/composer#12015 for details.

I identified this IFS line as causing the issue.. But it was introduced here
symfony/symfony@e9e0c07 (cc `@GromNaN`) probably for a good reason. So I don't think this is mergeable as is, but we should see what can be done to set IFS where needed per process call and not change it globally like that.
