It seems the terminfo library on some systems (OS X, Linux) may emit the sequence \e[x to reset to default attributes. Apart from using the zero-command, this escape sequence allows many more operations, such as setting ANSI colors. I don't see this used anywhere, so this should be sufficient for now. This deficiency was spotted by the Debian GNU/kFreeBSD. They have their own patch, which is slightly flawed in my opinion. I don't know why they never reported this issue to us. MFC after: 1 week
