I feel like the ancient `git revert` script is not at all in line with
current standards and sets people up for failure.  This one at least
has a commit message.  But
1) The subject doesn't have a correct patch prefix.
2) "commit fd48124e09825797bdc8ff0120f2401030c618ee" is not human
   readable or how we describe commits these days with a 12 char hash.
3) There is no fixes tag.
