You have to do that in any language. Ever worked on a C/C++ files where the indentation is different from your settings? I see only 2 choices: either you temporarily adapt your settings, or you just cringe your way through.

The third alternative (use your own settings anyway), is just lazy and mean.

There's an easy solution. First, either forbid or mandate tabs for indentation. Second, forbid trailing whitespace. That way all spaces will be visible.
