I don’t see how this, in any way, correlates to what a particular programmer’s preference is.
What I see is that most IDEs automatically replace the TAB (0x09) character with a set number of spaces (0x20). C is about 50–50 in this regards, RB completely, and Go — not at all.
What is very enlightening is the code used to comb through the data and develop the results. Thanks for publishing the material.
