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.
