/// <remarks>
/// Parse the committer identity from the raw buffer.
/// <p>
/// This method parses and returns the content of the committer line, after
/// taking the commit's character set into account and decoding the committer
/// name and email address. This method is fairly expensive and produces a
/// new PersonIdent instance on each invocation. Callers should invoke this
/// method only if they are certain they will be outputting the result, and
/// should cache the return value for as long as necessary to use all
/// information from it.
/// <p>
/// RevFilter implementations should try to use
/// <see cref="NGit.Util.RawParseUtils">NGit.Util.RawParseUtils</see>
/// to scan
/// the
/// <see cref="RawBuffer()">RawBuffer()</see>
/// instead, as this will allow faster evaluation
/// of commits.
/// </remarks>
/// <returns>
/// identity of the committer (name, email) and the time the commit
/// was made by the committer; null if no committer line was found.
/// </returns>
