Problem:    Lisp word only recognized when a space follows.
Solution:   Also match a word at the end of a line.  Rename the test.  Use a
            compiled function to avoid backslashes.

Keep the old Test_lisp_indent().

Problem:    Reading beyond the end of the line with lisp indenting.
Solution:   Avoid going over the NUL at the end of the line.

Cherry-pick Test_ex_mode() changes from Vim patches 8.2.{0342,0347}.
Reorder test_expand_func.vim to match upstream.

Does not include listener_*() functions.

js_*() functions are N/A.

json_encode() and json_decode() didn't include tests; add some anyway
(to json_functions_spec.lua).

test_lua.vim isn't included yet, so add tests to luaeval_spec.lua.

Problem:    Still old style tests.
Solution:   Convert serveral tests to new style. (Yegappan Lakshmanan)
