Updates since v2.5
------------------
UI, Workflows & Features
* An asterisk as a substring (as opposed to the entirety) of a path
component for both side of a refspec, e.g.
"refs/heads/o*:refs/remotes/heads/i*", is now allowed.
* New userdiff pattern definition for fountain screenwriting markup
format has been added.
* "git log" and friends learned a new "--date=format:..." option to
format timestamps using system's strftime(3).
* "git fast-import" learned to respond to the get-mark command via
its cat-blob-fd interface.
* "git rebase -i" learned "drop commit-object-name subject" command
as another way to skip replaying of a commit.
* A new configuration variable can enable "--follow" automatically
when "git log" is run with one pathspec argument.
* "git status" learned to show a more detailed information regarding
the "rebase -i" session in progress.
