/**
 * Parse the commit message and return the first "line" of it.
 * <p>//from w w  w . j  a v a2s  .c  om
 * The first line is everything up to the first pair of LFs. This is the
 * "oneline" format, suitable for output in a single line display.
 * <p>
 * This method parses and returns the message portion of the commit buffer,
 * after taking the commit's character set into account and decoding the
 * buffer using that character set. This method is a fairly expensive
 * operation and produces a new string on each invocation.
 *
 * @return decoded commit message as a string. Never null. The returned
 *         string does not contain any LFs, even if the first paragraph
 *         spanned multiple lines. Embedded LFs are converted to spaces.
