resize command sets lba flag and resizing the extended partition

[Sven Hartrumpf]

Hi. Why does "resize" set the flag "lba"?

(parted) p

In addition, I was surprised that resizing an extended
partition works although its logical partitions are
mounted. If this is a feature, one could add a sentence
to the description of "resize". (It simplifies my
massive hard disk reorganization substantially :-) )
