Documentation change suggestion

The man page for pg_dumpall could use a small change. The description of
the "-c" option says
-c, --clean
Clean (drop) database before creating schema.
For a while, I thought it meant that it was going to clean the database
that I was dumping, not adding commands to clean the database into the
file for when I restored it. I think that should be clarified a bit.
