hi ansgar,

nope this is no bug, rather a misconception from the begining. as it is 
not trivial task to change the commaseperate list into a mm-realation 
(think of all extension relieying on that datastructur) it has not been 
refactored till today.

but you could solve your problem easily. just alter the db field 
fe_groups to a field length fitting your needs. best practice to do 
this, is doing it with an extension. set the tca modification 
(pages.columns.fe_group.config.maxitems)in ext_tables.php and db in 
ext_tables.sql. so you are future proof and update save.
