So Git wont garbage collect a changeset if it is referenced by a tag? Seems quite sensible :-)

I see... You must be talking about the situation where we have

[A] --- [B] --- [T] --- [C] \ [X] --- [Y] --- <Z>

and T is the changeset that adds a tag for Y and Z is dead. If I clone this, I will only get A, B, T, and C and the .hgtags file will still reference the unknown Y.

Perhaps this suggests that it is a very bad idea to make a tag on one branch that refers to a changeset on another branch (again, "branch" means topological branch here). The normal case where you do

hg tag 1.0

to tag the current working copy parent revision works fine -- if you have the tag, then you also have the changeset it refers to.

So can we forbid tags that "cross branches" like this?
