I use git log -L :functionname:path to show a function history. But it show nothing even when the functionname is in the file.

Here is the gitattributes config

$ cat ~/.gitattributes
*.php diff=php

With grep, it shows the funcitonname in the file file.

$ grep newSearchByNameSongList app/Http/Controllers/SongController.php
    public function newSearchByNameSongList(Request $request) {

But git log -L cannot match it

$ git log -L :newSearchByNameSongList:app/Http/Controllers/SongController.php
fatal: -L parameter 'newSearchByNameSongList' starting at line 1: no match

Here is the git version.

$ git version
git version 2.34.1.windows.1
