I was going to suggest that you could accomplish this more easily
directly in shell (without employing `awk`):
{
echo start &&
printf "create refs/heads/branch-%d HEAD\n" $(test_seq 0 9999) &&
echo commit
} >input &&
but then I realized that that could potentially run afoul of
command-line length limit on some platform due to the 0-9999 sequence.
