I pushed a slightly different version as
50d5bb1f3e3f080212436db1b8666d061a8ae1d2, mostly avoiding the extra
‘stat’ call induced by ‘file-exists?’.

Thanks,
Ludo’.

When git-predicate is used on an active worktree, some files in the
index might not exist on the filesystem.  Instead of failing with "No
such file or directory", these should be ignored.

* guix/git-download.scm (git-predicate): Skip missing files.
