common/menu.c used printf() in a number of places to print user
provided, constant strings (like the "title" string). printf() is
dangerous here for example in case the user unwittingly embeds some
'%' caracters that printf() would interpret as formatting and then
pick up random arguments. Use puts() instead.
We also omit the trailing ':' in the title line - if a user wants
this, he can provide it as part of the title string.
