-------- From: Elias Oltmanns <eo@nebensachen.de> Subject: Make sure that interrupt characters get through reliably
Since commit ec5b1157f8e819c72fc93aa6d2d5117c08cdc961, users have been unable to interrupt interactive processes reliably by pressing CTRL+C. This patch reverts the original commit except for the most important part: actually echoing ^C is preserved.
