2590 will be inserted into the summary just like information from any other
2593 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2594 with care. For reasons of efficiency, Gnus will compute what column
2595 these characters will end up in, and \"hard-code\" that. This means that
2596 it is invalid to have these specs after a variable-length spec. Well,
2597 you might not be arrested, but your summary buffer will look strange,
2598 which is bad enough.
2600 The smart choice is to have these specs as far to the left as
2603 This restriction may disappear in later versions of Gnus.
