Failing to locate files properly

[RubenKelevra]

Environment

• Operating system: ArchLinux
• Git version: 2.38.1
• Mediawiki remote version:
• Install method:
• Site URL:
• Mediawiki site version: 1.40.0-wmf.14
• Git configuration:

remote.origin.fetchstrategy=by_ref
remote.origin.mediaimport=true
remote.origin.mediaexport=true

Issue

When doing a git init --bare, adding the remote and doing a git fetch origin I get a large amount of warnings that files cannot be located on the wiki.

But those warnings are wrong – the files exist on the wiki. So I think there could be an issue locating files with a space in the title, as the wiki shows them in the URL with _ signs instead of a space. While the error message prints the name out with a space sign.
