contacts: fix to work in subdirectories

sunshineco · gitster · commit 8fc9f0227e8e · 2013-09-17T22:16:22.000-07:00
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.
