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.

It shares a lot of code with the write path. Though, experiments with
common functions have shown that it would make the whole function even
harder to read. Maybe we could add some abstraction if we ever need
similar code on a third path.
