hmmm interesting... Here is what happens with --no-color:

    38708    33.2920  diff_tree
    23908    20.5628  base_name_compare
    18478    15.8926  decode_tree_entry
    8310      7.1473  find_pack_entry_one
    5654      4.8629  update_tree_entry
    2748      2.3635  pretty_print_commit
    1838      1.5808  get_one_line
    1460      1.2557  .plt

and wihtout it:

    2594     18.0893  pretty_print_commit
    1887     13.1590  get_one_line
    1574     10.9763  find_pack_entry_one
    967       6.7434  get_short_sha1
    892       6.2204  parse_commit_buffer
    863       6.0181  lookup_object
    595       4.1492  strbuf_grow
    440       3.0683  insert_obj_hash

Why on earth does --no-color has such a different code path ...
