"--full-name" to be default. This may cause regressions on
scripted users that do not expect this new behaviour.
* "git imap-send" learned to ask the credential helper for auth
material.

* "git merge" without argument, even when there is an upstream
defined for the current branch, refused to run until

+ * An experimental format to use two files (the base file and
