bdiff: avoid pointer arithmetic on void*

MSVC 2008 complains:

  mercurial/cext/bdiff.c(106) : error C2036: 'void *' : unknown size
  mercurial/cext/bdiff.c(107) : error C2036: 'void *' : unknown size

Maybe it's a gcc extension?

Create a repo, set the username to something more than 255 bytes, then run hg amend on it.

  $ unset HGUSER
  $ cat >> $HGRCPATH << EOF
