Improve coding style, variable names, data.c, sequence.c src/ChangeLog addition: 2013-08-05 Aidan Kehoe <kehoea@parhasard.net> * data.c: * data.c (Fcar): * data.c (Fcdr): * data.c (Fmake_weak_box): * data.c (Fweak_box_ref): * data.c (init_marking_ephemerons): * data.c (continue_marking_ephemerons): * data.c (finish_marking_ephemerons): * data.c (prune_ephemerons): * data.c (zap_finalize_list): * data.c (ephemeron_equal): * data.c (ephemeron_hash): * data.c (Fmake_ephemeron): * data.c (Fephemeron_ref): * data.c (Fephemeronp): * sequence.c: * sequence.c (Fcopy_tree): * sequence.c (Freplace): Improve coding style here; #'car and #'cdr accept lists, not just cons cells, update their argument names to reflect that. Follow coding conventions in the weak box and ephemeron code. Don't needlessly abbreviate in copy-tree, use argument names from Common Lisp in #'merge and #'replace. Document ALIST better in #'nsublis, #'sublis.

Here we have notes about the conversion to GPLv3. Things left to do,
things to check, etc...
