Subject: Getting path to a file from arbitrary project directory

Hello! I'm trying to solve a simple problem: while I am inside an arbitrary project directory, I want to get a path to a file `filename.c` located elsewhere in the same project.¹

One way to implement that is with a command chain:

	cd $(git rev-parse --show-toplevel) && git ls-files --full-name -- "*filename.c"

But it is pretty clunky, because that requires you to modify state (changing current directory). It may not matter though, but I'm just wondering if there's a better way to do that, something like `git ls-files --top -- …`, or anything like that? Haven't found nothing similar in `man git-ls-files`.

As a separate note, this doesn't work:

	ls-files --full-name -- $(git rev-parse --show-toplevel)"*filename.c"

1: the usecase is I have a Emacs helper function to pick up a an aribtrarily mangled path to a file in the project from the primary clipboard and open that file. It's often "mangled", because gdb prints it with `../`, then logs print no path whatsoever, just a filename… So it's generally useful to have.
