Description:        sourceline in pg_settings indicates wrong number
Details:
Hi,
sourceline (in pg_settings) of the parameter line without '\n' indicates
wrong number as follows.
 $ nl $PGDATA/postgresql.conf
     1  shared_buffers = 32MB         <-- this line doesn't contain '\n'
 $ psql -c "SELECT sourceline FROM pg_settings WHERE name =
'shared_buffers'"
  sourceline
 ------------
           0
 (1 row)
On the other hand, if the line has '\n', sourceline indicates the correct
number.
 $ echo "shared_buffers = 32MB" > $PGDATA/postgresql.conf
 $ nl $PGDATA/postgresql.conf
     1  shared_buffers = 32MB         <-- this line contains '\n'
 $ psql -c "SELECT sourceline FROM pg_settings WHERE name =
'shared_buffers'"
   sourceline
 ------------
           1
 (1 row)
Is this bug?
