For some files, the ~ symbol will always be displayed

[onlycalm]

Perform the following operations to reproduce the problem:

1. Create new files main.c and com.h under the test directory structure. (test/main.c test/com.h)
2. The content of the document is arbitrary, for example

1
2
3
3
4
5

3. And then execute the instructions. (git init git add --all `git commit -m "test")
4. You will see that all lines in com.h display the ~ symbol
   

It should not display the ~ symbol.The prompt for the main.c file is normal.
I also found similar problems in my other warehouses, some of the file prompt is abnorma.

The following projects reproduce this problem
test.zip

Does this only happen if the file is com.h? com is a special device in Windows, so it may be related to that.

The results of :SignifyDebug would be helpful.

I have the same problem with a file named scanner.py. For me it displays "!" which also means modified line. I get

git diff --no-color --no-ext-diff -U0 -- "scanner.py"

from :SignifyDebug.

The file is a fork of another repo and starts to show the "!" on opening the file. Though the fact that the file is forked shouldn't cause the issue. I'm using nvim on Windows but this also shouldn't break it as it works in other git directories.
