Nick Craig-Wood 52763e1918 local: when using -l fix setting modification times of symlinks #1152
Before this change it was setting the modification times of the things
that the symlinks pointed to.

Note that this is only implemented for unix style OSes.  Other OSes
will not attempt to set the modification time of a symlink.
