bug#23566: sql-sqlite: selecting database file is crippled)

[Rolf Ade]

I'm writing - I confess in the hope to rise attention to that bug - to
add emphesis to the current state. At the moment one needs a
configurateion like

(setq sql-sqlite-login-params '((database :file nil)))

for a pleasant experience with sql-sqlite.

This is low hanging fruit. Even just changing the default of
sql-sqlite-login-params to something like above would be a benefit
for most users.
