Indentation style

If that's the case, you're just not using the right keys to move around
the source code. :-) In Vim, keys like W/B, +/- etc. ignore whitespaces
anyway, and Emacs has equivalents. Rumour has it there are other editors
out in the wild, but then, some people believe anything... ;-)

I am aware this is a sensitive subject, but looking at the last 35+
years, I personally found that the only reliable way to avoid whitespace
related hassle is to stick to spaces only. I am not in a position to
decide this, of course, but I am glad that Python [1] even comes with a
command line option which turns mixed indentation into errors, making it
easy to spot these situations.
