Handle symlinks graciously
This patch converts a stat() to an lstat() call, thereby fixing the case when the date of a symlink was not the same as the one recorded in the index. The included test case demonstrates this. This is for the case that the symlink points to a non-existing file. If the file exists, worse things than just an error message happen.
