minor issue in createdb 8.0.0beta4

Hi !

I discovered this particular feature in "createdb" tool 8.0.0beta4
running on Win32 Platform:

-------------------- Cut And Paste ---------------------------

c:\windows> createdb testdb;
CREATE DATABASE

c:\windows> psql testdb
psql: FATAL:  database "testdb" does not exist

c:\windows> psql testdb;
Welcome to psql 8.0.0beta4, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

Warning: Console codepage (850) differs from windows codepage (1252)
         8-bit characters will not work correctly. See PostgreSQL
         documentation "Installation on Windows" for details.

testdb;=# \l
        List of databases
   Name    |  Owner   | Encoding
-----------+----------+-----------
 template0 | postgres | SQL_ASCII
 template1 | postgres | SQL_ASCII
 testdb;   | silvio   | SQL_ASCII
(4 rows)

testdb;=#

-------------------- Cut And Paste ---------------------------

As you can see, createddb doesn't skip the semicolon after the
database's name, so you have a db name ending with semicolon. This is
not a problem really, but this happens only in this version/platform.

Thanks you all guys.
