[issue465] abusive strips on merged branches

[Phil]

New submission from Phil <hg.bt.web at secdev.org>:

When two heads are merged, if the younger is striped, the other is abusively
deleted, and without backup!

 /|
2 |
| 1  <-- strip here.

0

Recipe:
hg init
touch foo
hg add foo
hg commit -m add
echo bar1 >> foo
hg commit -m bar1
hg update 0
echo bar2 >> foo
hg commit -m bar2
hg merge
hg commit -m merge
hg strip 1
There you've lost rev2 forever and the bundle is not even usable anymore.

Tested with hg 0.9.1 and 0.9.3.
