Hi to all dvtm users,
i wrote a little'n simple routine which allow to lock the screen
until a passphrase has been inserted. It's doesn't deal with encrypted
key (that's because i don't need it; it's quite easy to implement, btw).
I hope someone else (other than me) will found it useful too.
In the attached patch i also removed the draw() function which is unused
at all.
Hope this help.
