* "git clone --dissociate" learned that it can be used even when
"--reference" was not used at the same time.
+ * "git blame" learnt to take "--first-parent" and "--reverse" at the
+ same time when it makes sense.
+
+ * "git checkout" did not follow the usual "--[no-]progress"
+ convention and implemented only "--quiet" that is essentially
+ a superset of "--no-progress". Extend the command to support the
+ usual "--[no-]progress".

Performance, Internal Implementation, Development Support etc.
* The implementation of "git mailinfo" was refactored so that a
mailinfo() function can be directly called from inside a process.
+ * With a "debug" helper, debugging of a single "git" invocation in
+ our test scripts has become a lot easier.

Also contains various documentation updates and code clean-ups.

+ needs to release resources itself, which it forgot to do.

+ list of alternate object databases, but the code to do so forgot to
+ correctly initialize the list.

+ * The code to prepare the working tree side of temporary directory
+ for the "dir-diff" feature forgot that symbolic links need not be
+ copied (or symlinked) to the temporary area, as the code already
+ special cases and overwrites them. Besides, it was wrong to try
+ computing the object name of the target of symbolic link, which may
+ not even exist or may be a directory.
