Ah, good to know.

That's using an evil rewrite of history, though.

Yes, I'd say it's not worth the trouble (for the C++-code; again, for
R code, the answer may be different). My impression is that nowadays the
holy war between tabs and spaces has cooled down, considerably. Probably
because modern editors are both, smart enough to allow indenting with
four spaces at a single key-press, _and_ to distinguish tabs and spaces,
visually.

I do confess there are some instances of mis-used tabs in RKWard,
though, i.e. to align end-of-line comments, which is simply wrong. I
never cared enough to figure out, how to replace those.

Again, though, _if_ we were to change tabs to spaces, there would be
more style questions to take care of at the same time. Things like
{} on the same line as if/else, or on different lines, spaces inside
and outside parentheses, etc. Not sure, if git blame -w could handle
all of these...

Regards
Thomas
