This patch adds a function to LineEditor that takes the current shell buffer, searches PATH for the first program that starts with that buffer and then compares that to any other programs starting with the buffer to remove any mismatching characters off the end. The result is appended to the buffer. This may be faster with a data structure but that seems overkill.
