Subject: gitk: Fix "blame parent commit" with separate work tree
X-Git-Url: http://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=0a2a979310c1ebc43d460fd8564981c9b3b99f07;p=gitk

gitk: Fix "blame parent commit" with separate work tree

Running "blame parent commit" currently brings up an empty blame view
when the the work tree is not the parent of the git directory.  Fix it
by feeding git-blame paths relative to $GIT_WORK_TREE instead of
"$GIT_DIR/..".
