From Burkhard Plaum:

Browse Source 
1. Fix a crash, which happened when cdtext_get() was called for an emtp=
y
   (i.e. NULL) field.

2. Add another function cdtext_get_const(), which returns a const point=
er
   and avoids too much strcpying (apps may want only to TEST if a
   field is present or have their own string management routines).
