It just occurred to me that I have some code to get a line of input,
if you (this directed at Nicolas :-)) don't fancy rolling your own.
It's in zgv - cm_getline() in src/3deffects.c. (You'll probably need
bits from font.c and readnbkey.c too.) If you want to see what it's
like, try shift-g when in the file selector.
