ossfuzz managed to create a scenario which triggers an `assert`.
This fixes it, by giving +1 more space for the backward search pass.

finally, a version that generalizes well
...
While it's not always strictly a win,
it's a win for files that see a noticeably compression ratio increase,
while it's a very small noise for other files.
Downside is, this patch is less efficient for 32-bit arrays of integer
than the previous patch which was introducing losses for other files,
but it's still a net improvement on this scenario.

works great on pathological arr[u32] examples

improve high compression ratio for file like #3793
...
this works great for 32-bit arrays,
notably the synthetic ones, with extreme regularity,
unfortunately, it's not universal,
and in some cases, it's a loss.
Crucially, on average, it's a loss on silesia.
The most negatively impacted file is x-ray.
It deserves an investigation before suggesting it as an evolution.

made playTests.sh more compatible with older versions of grep
...
replaced `\+` by `*`.
`\+` means `[1-N]`,
while `*` means `[0-N]`,
so it's not strictly equivalent
but `\+` happens to be badly supported on some flavors of grep,
and for the purpose of these tests, `*` is good enough.

it makes the test script more portable across posix systems
