Bug Description
SRU justification:
Impact: Selection on a UTF-8 console can lead to memory corruption. This fix came down through 2.6.27.15 but I think it is simple ad important enough to add to Hardy as a SRU.
Fix: Change memory calculation to add the additional character before multiplying.
Testcase: When memory redzones are enabled, a redzone corruption is reported.
When they are not enabled, trashing of random memory occurs.
