Description of defect
The description for File::truncate() and FileHandle::truncate() is wrong.
Both claim that "the extended area appears as if it were zero-filled."
However, at least FATFileSystem on SD card just adds random bytes at the end of the file.
I assume that this is wanted for performance reasons. But this stands in conflict to the description of the function.
Please correct the description to avoid wrong assumption here.
