for-each-ref: Fix --format=%(subject) for log message without newlines
'git for-each-ref --format=%(subject)' currently returns an empty string if the log message does not contain a newline. This patch teaches 'git for-each-ref' to return the entire log message (instead of an empty string) if there is no newline in the log message.
