🐛 git grep --heading breaks long paths

[pre]

Long paths get broken by delta with git grep --heading. There's no real truncate, the path is as long as before, but one - character is replaced with :

Reproduction:

mkdir /tmp/repro
cd /tmp/repro
git init
mkdir -p first/second/third/fourth/longer-path-which-triggers-truncate
echo 'hello truncate' > first/second/third/fourth/longer-path-which-triggers-truncate/example.txt
git add .
git commit -m test

git grep --heading hello

Actual output ("longer:path"):

first/second/third/fourth/longer:path-which-triggers-truncate/example.txt
1:hello truncate

Expected output ("longer-path"):

first/second/third/fourth/longer-path-which-triggers-truncate/example.txt
1:hello truncate

.gitconfig

[core]
  pager = delta

Seems to be the same issue as the following from 3 years ago:

• 🐛 grep --heading output is incorrect #1197

Is there a more recent workaround available?

[pre]

As a workaround, I removed pager = delta from .gitconfig and replaced my existing git grep alias with ripgrep:

• gg() { rg --json $* | delta }
