cttyhack: handle multiple consoles found in sysfs

2012-02-04T20:55:01Z

If multiple consoles are found from the sysfs file, cttyhack fails:

cttyhack: can't open '/dev/tty0 ttyS0': No such file or directory

In such cases take the last one as the kernel will use that one for
/dev/console.

shell_builtin_read: set cc[VMIN] to 1; lineedit: don't clear c_cc[VINTR]

2012-01-15T21:58:06Z

First change fixes "read -n NUM". Apparently poll() won't report
data availability if cc[VMIN] > 1 until there are at least cc[VMIN] bytes.

cttyhack: print detected ctty name when called without parameters

2011-10-31T12:18:44Z

Sometimes there's a need to figure out the controlling tty from a shell
script, for example, to obtain a line for getty. In this case it's easier
to call cttyhack than trying to repeat some of the cttyhack's logic.

function                                             old     new   delta
