So you won (being the first to implement it)... Thanks a lot.

I'll try, but I first need to ensure Ledger works here -- as told, I've now
inherited a Windows PC, after my laptop (Ubuntu) crash, and must redo some
painful configuration.

However, I still plan on really using Ledger, hence on testing your patch
(very) soon.

I don't know how you did it, but it appeared in the correct thread to me.

What I do, with Gnus, is C-u 1000 RET for entering the group, and fetching the
last 1000 posts (1000 is chosen depending on the date, and the estimated
amount of post over that period of time). Then, search on title...

Maybe (euh, no, certainly) some better methods do exist. Like keeping a link
to the post, and C-c C-o on the link.

Others?

Best regards,
  Seb
