Why not doing it the way I suggested: Introduce another spec for the
gnus-group-format-line which, if present, will limit the area
gnus-group-highlight-line will work on. This could be achived by
inserting an extent spanning the area with a special property, say
'do-highlight-here set. Gnus-group-highlight-line only needs to be
changed to 1) check if such an extent is present here. If not, proceed
as before. 2) If it is, highlight only the area that covers this
extent.

If I would know how to define another spec , say something along the
line %&{ ..... %} (this is not present already, is it?) I would do
this, but unfortunately I didn't really understand that part from a
quick glance...
