Hello. There is no rule in this moment to align the constant symbols in lisp, emacs lisp, lisp-interaction modes. For example: '( :stipple nil :background "LightBlue" :foreground "Black" :inverse-video nil (f p q r :name nil :server nil In case that the first symbol of the current line is a constant, the indentation will be: '( :stipple nil :background "LightBlue" :foreground "Black" :inverse-video nil (f p q r :name nil :server nil etc. It's not an exhaustive treatment, because there is not an exhaustive definition of this kind of alignement. I attached here the file diff which represents the output from cvs -d:pserver:anonymous@cvs.gnu.org:/sources/emacs diff emacs/lisp/emacs-lisp/lisp-mode.el and, in case that the code is accepted, a change log entry.
