From: Jeff Hostetler <jeffh...@microsoft.com> Version 7 addresses size_t and casting issues in strcmp_offset() and replaces shell test function with an awk expression to make the perf test run faster.
================ Teach add_index_entry_with_check() and has_dir_name() to avoid index lookups if the given path sorts after the last entry in the index. This saves at least 2 binary searches per entry. This improves performance during checkout and read-tree because merge_working_tree() and unpack_trees() processes a list of already sorted entries.
