And simply because nearly all (unix) editors still insert a hard tab
when pressing the tab key, and *mixing* tabs and spaces makes the
situation *really* unbearable, one really shouldn't use all spaces.
It's code, not graphics. If it's really horrible, any editor can be
configured to change the non-default tab-setting back to 8 if that's
the problem. Mine's set to 4. Primarily because I think 8 is too
much. Sometimes (roughly once every 2 years), that gives me problem.
It's exclusively when someone has consciously mixed tabs and spaces.
Using either or *never* gives any problem.

I beg to differ, for reasons stated multiple times elsewhere in this

Perhaps, but it's low-hanging fruit and since all spaces have its issues
too, why not just go with tabs?
