Version 4.0

• I changed the license to The Unlicense, which basically means you can do whatever you want with this script without having to tell me anything, nor state changes when modifying, nothing,.. Just use it, and that is enough for me.

• When using GUI editor, on most systems that would have caused unchanged lines starting with red color or whatever color your grep is configured to, that is now fixed - No color at all.

• Again, when using GUI editor, it is needed to properly establish the location of a temporary directory, and to create a temporary file inside. These routines have been greatly enhanced.

• The script has been properly tested with dash shell successfully, and I plan on testing it more in-depth with version 5.0.

• POSIX-compliance and portability in general has been a bit increased.

• Fixed an error which would cause help (usage) not showing, (I used wrong variable name).
