[PATCH v2 21/23] contrib/subtree: Convert spaces to tabs and remove some trailing whitespace

[Paul Campbell <pcampbell@kemitix.net>]

From: Herman van Rink <rink@initfour.nl>

It's a nasty formatting only patch and I won't be surprised or too dissappiointed
if this doesn't make it. Or are the rules for this more lax for contrib? How else
can contrib be brought in-line with coding standards?
