This is not my code; I just moved it around during restructuring. But
how about the attached patch and the following change-log entry?

(nnir-compose-result): use `gnus-replace-in-string' instead of
`string-match', `match-string' and `substitute'

Christoph, can you verify that it still works for you? The changed
lines are irrelevant to the nnmaildir backend. You'll have to apply
the patch though; no more easy downloading of the full file :-):

(Of course, this was never intended to be a "distribution", just to
