Subject: [PATCH] subtree: initialize "prefix" variable

We parse the "--prefix" command-line option into the
"$prefix" shell variable. However, if we do not see such an
option, the variable is left with whatever value it had in
the environment. We should initialize it to a known value,
like we do for other variables.
