Thanks for all the hard work you put in on maintaining kernel documentation.

The manpages for strcat[1], scanf[2], and getopt[3] don't mention the fact that
using those functions can lead to buffer overflow security exploits.  The
Secure Programming HOWTO section about C/C++[4] explains how to avoid such
exploits when using these functions.

Please add a "BUGS" or "SECURITY" section to those functions' manpages, which
talks about security.
