Works fine (default value after out-of-range) :)

Still remains the other bug that does not allow to specify "last sector" 
that just fits the size in +sectors/+N(K|M|G).

Example:

Command (m for help): n
Partition type:
    p   primary (0 primary, 0 extended, 4 free)
    e   extended
Select (default p):
Using default response p
Partition number (1-4, default 1):
Using default value 1
First sector (2048-524287, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +255M
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): 
+261120K
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +522240
Value out of range.
Last sector, +sectors or +size{K,M,G} (2048-524287, default 524287): +522239
Partition 1 of type Linux and of size 255 MiB is set

Command (m for help): p
