Winter a19cd4ffb1 Revert "treewide: replace rev with tag"
This reverts commit 65a333600d5c88a98d674f637d092807cfc12253.

This wasn't tested for correctness with something like fodwatch [0],
and should not have been (self-)merged so quickly, especially without
further review.

It also resulted in the breakage of at least one package [1] (and that's
the one we know of and was caught).

A few packages that were updated in between this commit and this revert
were not reverted back to using `rev`, but other than that, this is a
1:1 revert.
