why does "git revert" commit even if i try to bail with ":q!"?

  never noticed this before ... when i do a regular "git commit" and
enter my "vi" edit session and change my mind, i can bail with ":q!",
regardless of what i've set up as a commit message, and i'll see:

  Aborting commit due to empty commit message.

however, i was just playing with "git revert" and, after i ran:

  $ git revert <commit SHA>

i was dumped into another vi edit session:

Revert "HTTP->HTTPS"

This reverts commit 2965b41fd84a1a76f56984ecdf6c123d1992730f.

# Please enter the commit message for your changes. Lines starting # with '#' will be ignored, and an empty message aborts the commit. # # On branch master # Your branch is up to date with 'rpjday/master'. # # Changes to be committed: # modified: book/01-introduction/sections/installing.asc #

  again, simulating that i changed my mind, i just typed ":q!", but
the revert went ahead, anyway. i tried again, this time completely
deleting all the lines from the commit msg (as the template
suggested), but the revert *still* completed after typing ":q!".

  it was only after deleting all the lines and using ":wq" that the
revert was cancelled:

  Aborting commit due to empty commit message.

that seems ... inconsistent. am i misunderstanding something?
