RFR - JDK-8200434 - String::align, String::indent (code review)

[Jim Laskey]

Please review the code  for  String::align and String::indent at the link below.

Notes:
	Includes a private version of String::isMultiline() which may be made into a public method at some future date
	Includes minor correctness clean up of StringLatin1.java, StringUTF16.java
