2592 will be inserted into the summary just like information from any other
2595 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2596 with care. For reasons of efficiency, Gnus will compute what column
2597 these characters will end up in, and \"hard-code\" that. This means that
2598 it is invalid to have these specs after a variable-length spec. Well,
2599 you might not be arrested, but your summary buffer will look strange,
2600 which is bad enough.
2602 The smart choice is to have these specs as far to the left as
