Trivial changes: whitespace and modes. Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>

9term: Add missing parentheses, preventing buffer overflow. (el-sr) is the string length and (sizeof wdir - strlen(name) - 20) is the buffer size. When the string length is greater than the buffer size, the beginning of the string is supposed to be trimmed to fit in the buffer size. Unfortunately a pair of parentheses were missing, pointing sr outside the buffer, and the for loop below then reads outside the buffer. For certain binary data printed in a window, it causes a segfault.

9term: set TERM=dumb instead of TERM=9term Everyone seems to assume that TERM != dumb implies ANSI escape codes are okay. In fact, many people assume that unconditionally, but it is easier to argue back about TERM=dumb than TERM=9term. This applies to acme win too, because they share the code.

9term, acme: autoscroll Ignore scroll/noscroll window setting. Instead, scroll when the write begins in or immediately after the displayed window content. In the new scrolling discipline, executing "Noscroll" is replaced by typing Page Up or using the mouse to scroll higher in the buffer, and executing "Scroll" is replaced by typing End or using the mouse to scroll to the bottom of the buffer.
