Why is indentation in empty lines bad?

Question

Every FOSS project I know has rules against trailing whitespace in code. But I think it\'s very natural to continue the current indentation on the next line:

int         


        

Answer 1

I think it boils down to "no redundant hidden surprise bytes in your code plz".

As @sarnold points out, redundant surprise bytes make patching and diffs unnecessarily messy.
