Thanks.
Note that this is harder to implement than one would naïvely think,
if one aims for a very generic solution, without walking the whole
history.
I personally think that it is OK to limit the scope to expressions
that start from the tip of ref and expressions that start with the
SHA-1 at the tip of ref, e.g.
master~12:Documentation
v2.6.11:arch/alpha
5dc01c595e6c6ec9ccda # tag v2.6.11
26791a8bcf0e6d33f43a:arch # tag v2.6.12
26791a8bcf0~12:arch # starting at 26791a8b and dig down
are OK, while forbidding the following:
c39ae07f393806ccf406 # tree of tag v2.6.11
9ee1c939d1cb936b1f98 # commit v2.6.12^0
9ee1c939d1cb936b1f98: # tree of commit v2.6.12^0
9ee1c939d1cb936b1f98:arch # subtree of commit v2.6.12^0
which will make it significantly easier to implement the necessary
validation in a robust way.
