Prior to revision 149be6a0072e, largefiles were saved in the local repository, even if it was using the share extension. After that change, all largefiles are now stored in the shared repository. However, the backward compatibility for existing largefiles already placed in the local repository was never tested, and has been broken since.

Create mirror repo, and pull from source without largefile:
|
|
"pull" is used instead of "clone" for suppression of (1) updating to
|
|
tip (= caching largefile from source repo), and (2) recording source
|
|
repo as "default" path in .hg/hgrc.

Update working directory to "tip", which requires largefile("large"),
