How to reproduce:

• In a file A, change a local variable in all upper case
• in a file b, rename a variable, but keep the name valid for our linter
• git add A; git commit -m test

Actual result:

• Warning that the commit can't be done, and to read AnkiDroid/build/reports/ktlint/ktlintMainSourceSetFormat/ktlintMainSourceSetFormat.txt to find why
• B was reverted!!!!!!!!!!!

Expected result:

• A warning that commit failed
• A still committed, B uncomitted.

I wanted to add a first part of the work first, and then the big part of the work. I lost more than two hours of work. I was not expecting "git commit" to delete anything.
