3093 will be inserted into the summary just like information from any other
3096 The %U (status), %R (replied) and %z (zcore) specs have to be handled
3097 with care. For reasons of efficiency, Gnus will compute what column
3098 these characters will end up in, and \"hard-code\" that. This means that
3099 it is invalid to have these specs after a variable-length spec. Well,
3100 you might not be arrested, but your summary buffer will look strange,
3101 which is bad enough.
3103 The smart choice is to have these specs as far to the left as
