1. Replace (delq nil (mapcar ....)) with analogous (mapcan ...)
forms; this is in non-dumped files, it was done previously in
dumped files.
2. Replace (delq FOO (copy-sequence BAR)) with (remove* FOO BAR),
where #'eq and #'eql are equivalent
3. Replace (delq FOO BAR) with (delete* FOO BAR), where FOO is not
a non-fixnum number. Saves a little space in the dumped file
(since the compiler macro adds :test #'eq to the delete* call if
it's not clear that FOO is not a non-fixnum number).

42 ;; Merged by esr with recent mods to Emacs 19 buff-menu, 23 Mar 1993 | |
43 ;; | |
44 ;; Modified by Bob Weiner, Motorola, Inc., 4/14/89 | |
45 ;; | |
46 ;; Added optional backup argument to 'Buffer-menu-unmark' to make it undelete | |
47 ;; current entry and then move to previous one. | |
48 ;; | |
49 ;; Based on FSF code dating back to 1985. | |
50 | |
51 ;;; Code: | |
444 | 52 |
428 | 53 ;;;Trying to preserve the old window configuration works well in |
54 ;;;simple scenarios, when you enter the buffer menu, use it, and exit it. | |
55 ;;;But it does strange things when you switch back to the buffer list buffer | |
56 ;;;with C-x b, later on, when the window configuration is different. | |
57 ;;;The choice seems to be, either restore the window configuration | |
58 ;;;in all cases, or in no cases. | |
59 ;;;I decided it was better not to restore the window config at all. -- rms. | |
60 | |
61 ;;;But since then, I changed buffer-menu to use the selected window, | |
62 ;;;so q now once again goes back to the previous window configuration. | |
