doesn't abort commit if user doesn't modify the template commit message

What steps will reproduce the problem?

1. set a template commit message
2. try doing a commit
3. click "Commit" without modifying the message

What is the expected output? What do you see instead?

The commit should be aborted, or a confirmation message to the tune of "You didn't edit the commit message. Proceed anyway?" should appear.

What version of TortoiseGit and Git are you using? On what operating system?

• TortoiseGit 2.10.0.0 (C:\Program Files\TortoiseGit\bin)
• git version 2.20.1.windows.1
• Windows 7 x64

Please provide any additional information below.

Here's what happens at the command line:

> git config commit.template C:\Users\user\commitmsg.txt

> vim hello.txt

> git commit hello.txt
(Vim opens, I don't modify the template, exit Vim and...)
Aborting commit; you did not edit the message.

That's similar to what Git does when you enter an empty commit message:

> git commit hello.txt
(Vim opens, I erase everything, exit Vim and...)
Aborting commit due to empty commit message.
