diffcore-rename: don't consider unmerged path as source Since e9c8409 (diff-index --cached --raw: show tree entry on the LHS for unmerged entries., 2007-01-05), an unmerged entry should be detected by using DIFF_PAIR_UNMERGED(p), not by noticing both one and two sides of the filepair records mode=0 entries. However, it forgot to update some parts of the rename detection logic. This only makes difference in the "diff --cached" codepath where an unmerged filepair carries information on the entries that came from the tree. It probably hasn't been noticed for a long time because nobody would run "diff -M" during a conflict resolution, but "git status" uses rename detection when it internally runs "diff-index" and "diff-files" and gives nonsense results. In an unmerged pair, "one" side can have a valid filespec to record the tree entry (e.g. what's in HEAD) when running "diff --cached". This can be used as a rename source to other paths in the index that are not unmerged. The path that is unmerged by definition does not have the final content yet (i.e. "two" side cannot have a valid filespec), so it can never be a rename destination. Use the DIFF_PAIR_UNMERGED() to detect unmerged filepair correctly, and allow the valid "one" side of an unmerged filepair to be considered a potential rename source, but never to be considered a rename destination.
