Fix erasing of unaligned regions

The erase (-E) feature is somehow a brute force method, but still, if we
are given a region to erase, we should make sure to restore surrounding
data if the erase block expands beyond the region.

Slight alteration from `master` commit: Guard free() from NULL pointers
to be regression safe even in case of broken libc.
