I don't know, I admit I'm very confused by the autoload logic, so you
lost me at preloaded.  Also have been away from Elisp for almost a year.

If I remove the autoload I get compilation errors in electric.elc or
align.elc (from make bootstrap). I might be doing something wrong. How
can I test the autoload dependecies without a full make bootstrap?

And then there's the problem Noam mentioned in elisp-mode.el.

But Noam's patch apparently fixes that, so here's his patch and mine for
a quick review from either of you if you don't mind. Tested with 'make
bootstrap'.

Thanks,
João

Subject: [PATCH 2/2] Fix default value of electric-pair-pairs and
 electric-pair-text-pairs

Fixes: debbugs:24901

A previous change, titled "Add support for curly quotation marks to
electric-pair-mode", attempted to add these characters to the default
value of these variables.  But it did so in a quoted list, preventing
evaluation of the relevant expressions and resulting in an invalid
format.

* lisp/elec-pair.el (electric-pair-pairs): Use backquote and comma.
(electric-pair-text-pairs): Use backquote and comma.
