2015-01-25

12:12
In the command-line shell, make sure stderr is unbuffered so that it automatically flushes. This has always been the case already for unix and on Windows when the output is a console, but apparently was not the case on Windows when the output was a pipe. (check-in: 2a9ea9b4 user: drh tags: trunk)
