As far as I read the code in question[1], this feature will work
if and only if you use `gnus-group-get-new-news-this-group' (M-g)
for a group that has the `mail-source' group parameter.  The code
requires the group name to get the group parameter, however there
is no opportunity to pass the group name to the code if you use
`gnus-group-get-new-news' (g).
So, we can call this a bug.  I have no idea to fix it, though.

This is not a real problem.  It's only that `G c' doesn't know
such a parameter.

Exactly.
