First entry of gitignore searched if it starts with BOM #2177
Description
What version of ripgrep are you using?
ripgrep 13.0.0
-SIMD -AVX (compiled)
+SIMD +AVX (runtime)
How did you install ripgrep?
pacman -S ripgrep
What operating system are you using ripgrep on?
Arch Linux
Describe your bug.
When a .gitignore starts with a BOM, ripgrep does not ignore the first entry of the .gitignore. git itself ignores the first entry.
What are the steps to reproduce the behavior?
$ echo "\xef\xbb\xbftest\nignoreme" > .gitignore && echo "test" > ignoreme
$ rg test
What is the actual behavior?
$ rg --debug test

What is the expected behavior?
It should ignore ignoreme because git does so as well. See e.g. git status.
