Yeah.  But couldn't we have that part issue a warning if -s had been set
on the command line?

Patch attached that issues a warning.

Turns out it wasn't so contorted. Updated patch attached that only warns in the exact cases where the setting is ignored, and the warning says how it's actually setting the scale. I tested all the run types and it correctly complains only when warranted, samples:

$ ./pgbench -s 200 -i pgbench
creating tables...
10000 tuples done. ...

$ ./pgbench -s 100 pgbench
Scale setting ignored by standard tests, using database branch count
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 200 ...

$ ./pgbench -s 100 -f select.sql pgbench
starting vacuum...end.
transaction type: Custom query
scaling factor: 100 ...
