Thanks. Weird. Does
awk -v c=0 '$1 != "" {++c} END {print c}'
work better?

Some implementations of wc add a trailing space, causing
printf: 1 : invalid number
Using
printf "SHA $dir (%d entries, %d subtrees)\n" "$entries" $subtree_count &&
(with no quotes around $subtree_count) would avoid trouble, though
that's a little subtle.
Hope that helps,
