Ray Lai 669713d43f 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.

README.md

This is a port of many Plan 9 libraries and programs to Unix.

Installation

To install, run ./INSTALL. It builds mk and then uses mk to run the rest of the installation.

For more details, see install(1), at install.txt in this directory and at http://swtch.com/plan9port/man/man1/install.html.

Documentation

See http://swtch.com/plan9port/man/ for more documentation. (Documentation is also in this tree, but you need to run a successful install first. After that, "9 man 1 intro".)

Intro(1) contains a list of man pages that describe new features or differences from Plan 9.

Helping out

If you'd like to help out, great! The TODO file contains a small list.

If you port this code to other architectures, please share your changes so others can benefit.

Please use codereview(1) to prepare patches.

Git

You can use Git to keep your local copy up-to-date as we make changes and fix bugs. See the git(1) man page here ("9 man git") for details on using Git.
