The problem is that it is sometimes not clear to me what exactly has to
change.

Currently, the change to lread.c broke the grammar generation in CEDET.

The culprit is that

(read "( ,(cons $1 $3 ) )")

used to return

(\, (cons $1 $3))

but now returns

((\, (cons $1 $3)))

Does CEDET depend on some obsoleted feature here, meaning this should
rather be fixed in CEDET than emacs?
