Use DOC for dumped Lisp file names; Xref to source-lisp if readable, symbol-file lisp/ChangeLog addition: 2010-02-01 Aidan Kehoe <kehoea@parhasard.net> * loadhist.el (symbol-file): If #'built-in-symbol-file returns a Lisp file name, and source-lisp is readable, construct a full pathname to include that. Otherwise use lisp-directory, as we used to. * loadup.el: Delete load-history entries for those files in preloaded-file-list; unloading the associated features makes very little sense, and the symbol file information can be had from DOC.
