[bug-fdisk] fdisk and partition size

[Christian]

Hi, reading Libparted Api, I see that the function `ped_unit_parse'
accept strings linke: `+sizeKb', `+sizeMb', `+size%' and more.

Fdisk use this function when the user specify a size of a new partition 
begin with `+' character.
My question is: When is time to specify partition size fdisk print a 
message linke:

   partition size `+sizeKb' or `+sizeMb'?

But not inform the user that size can be exressed as a percentage like 
`+size%'. This
particular is for compatibility with Linux tools?
