Comment 10 for bug 568306

I agree with Kamilion (comment 8); as far as I am concerned the fix for this bug has introduced a major regression. Some things -- ssh X tunnelling for example -- do not work from inside a reattached screen session (as the environment variables set by ssh are not and cannot be carried into existing shells inside screen) and before this fix I frequently needed to detach the screen session in order to use the underlying remote shell.
