tree-diff: reuse base str(buf) memory on sub-tree recursionks/tree-diff-more
instead of allocating it all the time for every subtree in
__diff_tree_sha1, let's allocate it once in diff_tree_sha1, and then all
callee just use it in stacking style, without memory allocations.
This should be faster, and for me this change gives the following
slight speedups for
git log --raw --no-abbrev --no-renames --format='%H'
navy.git linux.git v3.10..v3.11
before 0.618s 1.903s
after 0.611s 1.889s
speedup 1.1% 0.7%
