[HACKERS] Confusing error message in pgbench

I found an error message in pgbench is quite confusing.

pgbench -S -M extended -c 1 -T 30 test
query mode (-M) should be specified before any transaction scripts (-f or -b)

Since there's no -f or -b option is specified, users will be
confused. Actually the error occurs because pgbench implicitly
introduces a built in script for -S. To eliminate the confusion, I
think the error message should be fixed like this:

query mode (-M) should be specified before transaction type (-S or -N) or any transaction scripts (-f or -b)

Patch attached.

Best regards,
