I've got two alternative solutions for this issue.
The first one is less intrusive: use the 'command' builtin to tell
the shell to ignore shell functions and aliases and just run the ls
command.
diff --git a/contrib/completion/git-completion.bash

echo "${i/.url*/}"
But then it got me thinking... Notice how much effort we spend just
to get the list of remotes? We could just run 'git remote' directly
instead...

I prefer the second one ;)
Best,
