[asterisk-users] Explication for ast_safe_system

[C F]

Never noticed the c is next to the n, however thinking about it, the c
is to the f what the n is to the j. which might make for an easy
mistake. I guess if you put only your right hand on the keyboard, and
mistake the f for the j on your right index finger that it could
happen easyly.
