The latter is not exactly a shortcut for the former.  You can try it at any
merge commit, and you will see different log. For instance, in Git repo:

$git rev-list 7ac749c^..7ac749c
7ac749c96d143ba4f76723959892cbaddbe8ed07
006f31d77f3dd5f813557c2839b39b2aaa22b925
53b22a9e45161004ff3260782abc4ee2a5b3e730
872354dcb3ce5f34f7ddb12d2c89d26a1ea4daf0
bc7c73e29cfb38232b5b6b1d1e8d59e7145a9860

$git rev-list 7ac749c^!
7ac749c96d143ba4f76723959892cbaddbe8ed07

So, I believe, rev^! means --first-parent rev^..rev
