Add unstripped option to keep newlines at beginning/end

[Jeehut]

Currently using the combination of BartyCrouch and PhraseApp results to some issues with newlines. The problem is that PhraseApp keeps no newline at the top of the file and two newlines instead at the bottom of it. BartyCrouch currently keeps each one newline at the top and bottom.

The requested feature would be a new command line option to keep the surrounding newlines (and other whitespace characters) the the top and bottom of the file. It could be called unstripped or -u as strip is typically a method on Strings that removes whitespaces from the beginning and end.

Version 3.7.0 attempts to fix this version with the new unstripped option. Closing this.
