[issue2655] 1-byte status file causes most hg commands to fail

[huazheng]

New submission from huazheng <geoffreyzheng at yahoo.com>:

Steps to reproduce:
- cd <any hg repo with at least one changeset and no mq patch>
- cd .hg/patches; echo > status; cd -
- hg log

In both 1.5 linux and 1.7.2 Windows, it fails, though in different places.

Removing the empty status file fixes the problem.

I can't recall exactly how I got into the situation, but I suppose mq
shouldn't fail for such a simple case.
