patch 9.1.0692: Wrong patlen value in ex_substitute()

Browse Source 
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.

closes: #15565
