bug#25333: 25.1; electric-quote-local-mode has no effect in message mode

[Christophe Troestler]

When turning electric-quote-local-mode on in message-mode, one expects
` 
to be turned to ‘ and the like.  However, it does nothing
outside 
quotations (lines starting with ‘>’ and the like).  It
seems to be 
because ‘comment-use-syntax’ is left as
‘undecided’.  Shouldn’t it set 
to ‘nil‘ (for some parts only if needed)?
