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`.
When a command expects pathspecs as arguments, then in general the leading ':/' magic means the root of the working tree (not sure where it is documented, though), i.e. you could try this:
git ls-files --full-name ':/*filename.c'

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.
