It was stated, perhaps even by me but no longer sure of this (it looks like my style) that after the program is terminated the terminal might not be sane and one could do 'stty sane', 'reset' and other things. Instead I have changed the code to just call endwin() and removed that information instead. This way the user should not be burdened by it. The alt code that I had added earlier on also has this fix. The markdown files have not been completely checked but both README.md and design.md have had some fixes applied. The thanks file also points out that Yusuke's fix applies the suggested fix for select(2) found in the README.md.
