2597 will be inserted into the summary just like information from any other
2600 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2601 with care. For reasons of efficiency, Gnus will compute what column
2602 these characters will end up in, and \"hard-code\" that. This means that
2603 it is invalid to have these specs after a variable-length spec. Well,
2604 you might not be arrested, but your summary buffer will look strange,
2605 which is bad enough.
2607 The smart choice is to have these specs as far to the left as
