Hello,

I use a little patch[1] since years to split groups not only on group
parameters from “newsrc” but from “gnus-parameters” too.

I found the later easier to manage.

Following is my pull request, if you want it.

Regards.

The following changes since commit 23c6fe6e28b8b6f356bae60e2fc773c41cd8b540:

  gnus-msg.el (gnus-setup-message): Fix last commit (2013-12-09 00:35:04 +0000)

  Use `gnus-parameters' in `gnus-group-split-fancy' (2013-12-14 15:10:06 +0100)

----------------------------------------------------------------
Group splitting does not use `gnus-parameters'

I found `gnus-parameters' easier to manage than `newsrc':

- human readable file
- file is versionned

This patch add the `gnus-parameters' to `newsrc' structure before
building split.
