2574 will be inserted into the summary just like information from any other
2577 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2578 with care. For reasons of efficiency, Gnus will compute what column
2579 these characters will end up in, and \"hard-code\" that. This means that
2580 it is invalid to have these specs after a variable-length spec. Well,
2581 you might not be arrested, but your summary buffer will look strange,
2582 which is bad enough.
2584 The smart choice is to have these specs as far to the left as
2587 This restriction may disappear in later versions of Gnus.
2589 General format specifiers can also be used.
