There's a difference (isNull() only returns null for the first kind), but operator== \
says they are equal indeed, to avoid all those nasty bugs we had in kde3 where a null \
string (e.g. user entered nothing) and an empty string (e.g. as returned by config) \
were considered different (while for the user of a lineedit, it's really empty in \
both cases).
