There is a very useful feature in Bash where you can redirect the trace
enabled by `set -x` to a file descriptor *different* than 2. This comes
in particularly handy when validating the error output of commands, say,
in Git's test suite, while tracing at the same time.

It is such a useful feature, and very easily implemented.
