Documentation needed for re.split behavior regarding zero-width chars

[capocasa]

re.split behaves in an unexpected way which won't be changed, so the behavior needs to be documented.

#14468 (comment)

PRs are welcome

PR sounds more productive than documenting something odd; since there is some reasonable disagreement amongst libraries (see #14468 (comment)) I suggest starting with non-controversial fixes first; @capocasa do you want to close this and instead open a PR to fix #14468 ?

Agreed.

close this and instead open a PR to fix #14468

Maybe- would it be feasible to reopen it? And could possible issues have a target to select "1.x" or "dev"?

i reopened

And could possible issues have a target to select "1.x" or "dev"?

easiest is to target devel and backport on a best effort basis to 1.x
