2631 will be inserted into the summary just like information from any other
2634 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2635 with care. For reasons of efficiency, Gnus will compute what column
2636 these characters will end up in, and \"hard-code\" that. This means that
2637 it is invalid to have these specs after a variable-length spec. Well,
2638 you might not be arrested, but your summary buffer will look strange,
2639 which is bad enough.
2641 The smart choice is to have these specs as far to the left as
2644 This restriction may disappear in later versions of Gnus.
