Performance improvement on writing a large index
The index header consists of a 4-byte version number. The current
supported version numbers are 2 and 3. The code checks if any entries
are extended. If it finds any entries that are extended it picks version
'3', otherwise it chooses version '2'.
DirCache.java
-Changed the 'extended' check to exit early when any entry is considered
'extended' in the index.
(Of course, I maybe missing a bitwise optimization that is made in
the Java bytecode.)
