Unlike other git commands which work correctly at the top-level or in a
subdirectory, git-contacts fails when invoked in a subdirectory. This is
because it invokes git-blame with pathnames relative to the top-level,
but git-blame interprets the pathnames as relative to the current
directory. Fix this.
