(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.

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. Set termprog=9term or termprog=win for clients who need to know. R=rsc CC=r https://codereview.appspot.com/12532043

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.

Also just drop \r from output. It's a losing battle to keep turning it off. R=rsc http://codereview.appspot.com/2128042

- don't exit from a "child" note unless rc exited (code copied from 9term.c) - ignore writes to the tag; specifically " Send Noscroll" at startup. R=rsc CC=codebot http://codereview.appspot.com/181115
