vimX is easy to run and it hang in record after 226 iterations.

This is while executing pijul git. It hangs on commit 6bb683663, which contains a huge file change:

 runtime/spell/en.spl | 110576 ++++++++++++++++++++++++++++++++++++++++++++--------------------------------------------
 1 file changed, 55290 insertions(+), 55286 deletions(-)

flamegraph shows that the process “hangs” inside diffs::myers::diff_offsets.

EDIT: it actually succeeds but just takes an inordinate amount of time.

I created this to investigate more: https://nest.pijul.com/pijul/diffs/discussions/1

Fixed.
