[PATCH/RFC v1 5/6] combine-diff.c: remove a call to fstat() inside show_patch_diff()

[Kjetil Barvik <barvik@broadpark.no>]

Currently inside show_patch_diff() we have and fstat() call after an
ok lstat() call.  Since we before the call to fstat() have already
test for the link case with S_ISLNK() the fstat() can be removed.
