The doc. At least what you get is what I intended when I added this
(we had some real-world example for the use of this at the time, but I 
don't remember it anymore).

More about ${(l:e::s1::s2:)param}

[Bart Schaefer]

The info says:

`l:'EXPR`::'STRING1`::'STRING2`:'
     Pad the resulting words on the left.  Each word will be truncated
     if required and placed in a field EXPR characters wide.  The space
     to the left will be filled with STRING1 (concatenated as often as
     needed) or spaces if STRING1 is not given.  If both STRING1 and
     STRING2 are given, this string will be placed exactly once
     directly to the left of the resulting word.

`r:'EXPR`::'STRING1`::'STRING2`:'
     As `l', but pad the words on the right.

Apparently "the resulting word" is "the word before padding with STRING1":

zagzig<1> foo=77
zagzig<2> print -- ${(l:5::0::x:)foo}
00x77
zagzig<3> print -- ${(r:5::0::x:)foo} 
77x00

The doc phrasing led me to expect x00077 and 77000x.  What needs fixing,
the doc or the code?
