`align' doesn't mention the prefix arg in the doc string, but in certain
modes, different alignment rules are picked based on what prefix you
give to the command. For instance, text mode:
;; With a numeric prefix argument, or C-u, space delimited text
;; tables will be aligned.
(text-column
(regexp . "\\(^\\|\\S-\\)\\([ \t]+\\)\\(\\S-\\|$\\)")
(group . 2)
(modes . align-text-modes)
(repeat . t)
(run-if . ,(lambda ()
(and current-prefix-arg
(not (eq '- current-prefix-arg))))))
;; With a negative prefix argument, lists of dollar figures will
;; be aligned.
(text-dollar-figure
(regexp . "\\$?\\(\\s-+[0-9]+\\)\\.")
(modes . align-text-modes)
(justify . t)
(run-if . ,(lambda ()
(eq '- current-prefix-arg))))
It's also not clear why `M-x align' in text modes do nothing -- you
have to give it a prefix to make it do anything.
