Subject: [PATCH] console: add question-mark escape operator
Some termcaps (found using SLES11SP1) use [? sequences. According to man
console_codes (http://linux.die.net/man/4/console_codes) the question mark
is a nop and should simply be ignored.
This patch does exactly that, rendering screen output readable when
outputting guest serial consoles to the graphical console emulator.
