patch 9.1.0692: Wrong patlen value in ex_substitute()
Problem: Wrong patlen value in ex_substitute() (after 9.1.0426).
Solution: Compute patlen after finding end separator.
(zeertzjq)
Add a more explicit test. The test already passes as the only case
where a overlarge patlen value matters was fixed by patch 9.1.0689.
