some issues with dialog_ui.c

[Timothee Besset]

I have two small problems with dialog_ui.c code right now (the text based
installation):

The license dialog doesn't wrap text .. I am going to look that up, but if
anyone has some hints, I'd be happy to hear about it :-)

The dialogs are leaving black horizontal lines here, is it specific to my
terminal configuration or everyone is getting this? (this is not critical
enough to me yet, so I'm not planning to really look at it)
