The echo-to-terminal portions of ttyread and ttysend were actually doing the same thing. New function twrite() now handles this. The parameter show_ctrl determines whether control characters are shown as "^A". This was the only difference between tputc and techo, and techo is now unused and removed. (This commit should not change st's behaviour.) Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
