2576 will be inserted into the summary just like information from any other
2579 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2580 with care. For reasons of efficiency, Gnus will compute what column
2581 these characters will end up in, and \"hard-code\" that. This means that
2582 it is invalid to have these specs after a variable-length spec. Well,
2583 you might not be arrested, but your summary buffer will look strange,
2584 which is bad enough.
2586 The smart choice is to have these specs as far to the left as
2589 This restriction may disappear in later versions of Gnus.
2591 General format specifiers can also be used.
