master d73a104dd3 1/2: Be more lax when picking up prefixes for loaddefs

[Stefan Kangas]

branch: master
commit d73a104dd349fdf8de5ababa9ae53ea807b00bfb
Author: Stefan Kangas <stefan@marxist.se>

    Be more lax when picking up prefixes for loaddefs
    
    * lisp/emacs-lisp/loaddefs-gen.el
    (loaddefs-generate--compute-prefixes): Allow tabs and spaces before
    symbol name, so that "(defvar\tfoo-bar nil)" is properly picked up.
    Before this change, such a definition would be wrongly picked up as
    the symbol "nil".
