pg_dumpall --roles-only interact with other options

hi.

pg_dumpall --verbose --roles-only --no-schema --file=1.sql
pg_dumpall --verbose --roles-only --no-data --file=2.sql
pg_dumpall --verbose --roles-only --no-statistics --file=3.sql
pg_dumpall --verbose --roles-only --statistics-only --file=4.sql
pg_dumpall --verbose --roles-only --data-only --file=5.sql
pg_dumpall --verbose --roles-only --schema-only --file=6.sql

What should we expect for the above commands?
the current behavior is not good, i think, some even do not dump the
roles command.

I would expect the last three commands to raise errors, while the first three
should simply ignore the options (--no-schema, --no-data, --no-statistics).

This situation also happens to another pg_duampall option: --tablespaces-only.

what do you think?
