 The variables `sql-user', `sql-password', `sql-server', and
 `sql-database' can be customized.  They are used as the default values.
 Usernames, servers and databases are stored in `sql-user-history',
 `sql-server-history' and `database-history'.  Passwords are not stored
 in a history.
-
 Parameter WHAT is a list of the arguments passed to this function.
 The function asks for the username if WHAT contains symbol `user', for
 the password if it contains symbol `password', for the server if it
 contains symbol `server', and for the database if it contains symbol
 `database'.  The members of WHAT are processed in the order in which
 they are provided.
-
 In order to ask the user for username, password and database, call the
 function like this: (sql-get-login 'user 'password 'database)."
