This pull request aligns the indentation. So It will be able to improve
readability.
In this pull request the address part is filled with white spaces. The amount
of space is calculated from VM's logarithmic address size and lastly 2, which
is the length of "0x", is added.
I checked the output on 64-bit and 32-bit OS.
