Stock Mercurial can miss changes if:
- the timestamp is unchanged
- the size is unchanged
- the timestamp is NOT the time of checkout
In other words, you take a file Mercurial knows is clean, make a
size-preserving edit, then set the date back to its original date.
This is an issue we're not going to fix; it would make Mercurial an
order of magnitude slower for everyone to catch a very small number of
misbehaving apps/users.
It may also be possible to miss changes if a write to the file occurs
during checkout.
If you can reproduce the issue, please file a bug report, we may be able
to diagnose it. But reports after you've destroyed the evidence: not so
interesting.
