This should be closer to opendir(). The code in between,
invalidate_directory(), could have modified errno and we would print
incorrect message here.
But you can't simply move the whole "if (!cdir->fdir) { .. }" block up
either because we want to invalidate before returning -1, so perhaps
cdir->fdir = opendir(c_path);
if (!cdir->fdir)
warning_errno(_("could not open directory '%s'"), c_path);
if (dir->untracked) { ... }
if (!cdir->fdir)
return -1;
