I think the general understanding is that there is no consistent pattern
of spaces vs. tabs+spaces in effect, and that this is not an important
thing.

Way back in history, tabs+spaces was, I believe, universal, since it
saved on characters when the amount of RAM and disk space were a minute
fraction of today's.

I would ask, however, that a systematic attempt to convert to a
consistent spaces only is NOT made.  This fouls up diffs, giving the
impression of change where there is none.
