I still don't know if return (0, $null) is the right thing to do,
but in any case, I find the original flow easier to read, i.e. "we
notice a few cases we cannot do the main 'hash-object' thing this
function is meant to do and return early". I.e.
if (-l "$workdir/$file" || ! -f _) {
return (0, $null_sha1);
}
my $wt_sha1 = $repo->command_oneline('hash-object', "$workdir/$file");
my $use = ($sha1 eq $null_sha1) || ($sha1 eq $wt_sha1);
return ($use, $wt_sha1);
