patch 9.0.1710: scrolloff options work slightly different Commit: https://github.com/vim/vim/commit/4a8eb6e7a9df10f79bf95301ced012f0d6a13088 Author: Christian Brabandt <cb@256bit.org> Date: Sun Aug 13 19:43:42 2023 +0200 patch 9.0.1710: scrolloff options work slightly different Problem: sidescrolloff and scrolloff options work slightly different than other global-local options Solution: Make it behave consistent for all global-local options It was noticed, that sidescrolloff and scrolloff options behave differently in comparison to other global-local window options like 'listchars' So make those two behave like other global-local options. Also add some extra documentation for a few special local-window options. Add a few tests to make sure all global-local window options behave similar closes: #12956 closes: #12643 Signed-off-by: Christian Brabandt <cb@256bit.org>

Inserts 2 million lines with consecutive integers starting from 1
(essentially, the output of GNU's seq 1 2000000), writes them to Xtest
and writes its cksum to test.out.

We need 2 million lines to trigger a call to mf_hash_grow().  If it would mess
up the lines the checksum would differ.

cksum is part of POSIX and so should be available on most Unixes.
If it isn't available then the test will be skipped.

VMS does not have CKSUM but has a built in CHECKSUM - it should be used
