No, I didn't install this patch.  I don't use the nnfolder back end of
Gnus, so I can't really test it.

However I think we must do something about this dotless-i/dotted-I
problem because it seems to render Gnus unusable with big (nnfolder)
mailbox files in Emacs 22.

As Elias Oltmanns already has pointed out, the problem is that
nnfolder often does re-searches for "X-Gnus-Article-Number: "
(`nnfolder-article-marker').  Wrapping these calls inside ...

  (with-case-table some-case-table-without-dotless-i/dotted-I
    (re-search-forward nnfolder-article-marker ...))

... might be a possibility.  But there's no `with-case-table' and I
don't know enough about case table to develop a fix that doesn't break
anything else.

Bye, Reiner.
