pg_restore multiple --function options

Hi,

While looking at the pg_restore code, I noticed that while it supports 
specifying multiple --table options to restore several tables, it does 
not support multiple --function options. Or --index, --schema, or --trigger.

The support for multiple --table options was added in 9.3, in January. 
See

Was there a particular reason for only doing it for --table, or was it 
just an oversight or lack of interest? No doubt that --table is the most 
interesting one, but IMHO the other options should behave the same, for 
the sake of consistency.
