track time of soft link, not soft link target
In situations where soft links point to a location outside of the repository, TimestampMod complains with errors like this
*** TimestampMod: Get File Stat failed for Web/base/static/figures!
I forked this repository and have a fix that tracks the timestamp of soft links instead of their associated targets. For the life of me, I can not figure out how to issue a pull request (are they enabled?). Happy to refine however you deem fit.
