2467 will be inserted into the summary just like information from any other
2470 The %U (status), %R (replied) and %z (zcore) specs have to be handled
2471 with care. For reasons of efficiency, Gnus will compute what column
2472 these characters will end up in, and \"hard-code\" that. This means that
2473 it is invalid to have these specs after a variable-length spec. Well,
2474 you might not be arrested, but your summary buffer will look strange,
2475 which is bad enough.
2477 The smart choice is to have these specs as far to the left as
2480 This restriction may disappear in later versions of Gnus.
2482 General format specifiers can also be used.
