[PATCH] vc-list-files: Adjust the script to support git worktrees

[Erik Skultety]

Git's worktree feature creates a ".git" which refers to references from
the original (main) repository. This makes vc-list-files to fail for
worktrees since it checks for both file's existence and the file being a
directory. Checking for existence should be okay in this case, since the
script doesn't touch anything within ".git" directly. Instead, it
invokes git commands, which work from within a worktree nicely.
