[PATCH 1/1] hg.py: Fixed fetch failure that occurs when SRCREV is a tag.

[PATCH 1/1] hg.py: Fixed fetch failure that occurs when SRCREV is a tag.

[Jon Szymaniak]

Removed "-r REV" from hg clone invocation to fetch the entire repo,
rather than just the subset at the specified revision. This will ensure
that the specified tag exists for successive commands (e.g., the update
built on line 149.)
