Ooh, evil. I like it.

It's a rather expensive operation, but it does have the really nice 
property that it will show the date of the commit the tag is pointing to, 
rather than necessarily the date of the tag itself (which is not 
well-defined unless the tag is signed).

As you mention, "--simplify-by-decoration" will show merges too (unless it 
can linearize the tag history), but you can work around that by making the 
format be "format:%ai %d" where that '%d' shows the decoration of the 
commit, rather than the commit summary. Now the merges that aren't tagged 
stand out very clearly.

Of course, the above will just work for commit tags. If you've tagged a 
tree or a blob, the above gives you bubkis.
