unpack-trees: don't perform any index operation if we're not merging

René Scharfe · gitster · commit 97e5954bdcf4 · 2012-04-10T16:36:18.000-07:00
src[0] points to the index entry in the merge case and to the first
tree to unpack in the non-merge case.  We only want to mark the index
entry, so check first if we're merging.
