`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.
     (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.
     (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.
