i just realized i have that in my .vilerc -- just have never really used
it.  you can see that it cheats, with regard to the newline thing:  (the
"day" command prints a formatted date.)

    store-procedure insert-day
            insert-string "\n\n"
            previous-line
            filter-til goto-eol "day"
            previous-line
            join-lines
            join-lines
    ~endm
    bind-key insert-day M-d

i thought there was a way, but i'm not finding it.

i know you're asking a more general question, but there's also the
the &date function:
   | &date       | 2    | format 2nd param with 1st, like strftime.        |
