Subject: Avoid going past the end of route when a new one is set
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=2fec8b40d8cd953e36362773e440e50cc4f94a91;hp=2fec8b40d8cd953e36362773e440e50cc4f94a91;p=r2c2.git

Avoid going past the end of route when a new one is set

Calling stop_at(0) causes the block allocator to immediately resume
allocating blocks.  In certain circumstances this would cause an
allocation past the end of the route.
