The `printf` example is probably cleaner, thus preferable. For
completeness, though, I should mention that the `echo` example is, of
course, not quite correct. For the interpolation to work as intended,
it would need ${...}:
tree1=$(echo "100644 blob ${seq1}Qsequence" | q_to_tab | git mktree) &&
tree2=$(echo "100644 blob ${seq2}Qsequence" | q_to_tab | git mktree) &&
tree3=$(echo "100644 blob ${seq3}Qsequence" | q_to_tab | git mktree) &&
