[PATCH v4] Ensure compatibility with tree 2.0.

[Marius Bakke]

Tree 2.0 and later will unconditionally ignore all options and write
JSON data on file descriptor 3 when available, which causes problems
for the test harness and other scripts that use FD 3.  Work around by
closing descriptor 3 for the 'tree' command.

* Changes in v4:
  - Removed line breaks.

Thanks for the feedback, everyone.
