bug#2527: 23.0.91; abbrev-defs formating

[Nikolaj Schumacher]

Just a cosmetic issue, but previously the abbrev_defs looked like 
this: 

(define-abbrev-table 'c-mode-abbrev-table '( ("else" "else" 
   c-electric-continued-statement 0) ("while" "while" 
   c-electric-continued-statement 0) ...

Now the first two lines are on one very long line.

(define-abbrev-table 'c-mode-abbrev-table '(    ("else" "else" ...
   ("while" "while" c-electric-continued-statement 0) ...


In GNU Emacs 23.0.91.3 (i386-apple-darwin9.6.0, NS 
apple-appkit-949.43) of 2009-02-28 on thursday Windowing system 
distributor `Apple', version 10.3.949 configured using `configure
