Patch 8.2.0567

THIS IS STILL UNDER DEVELOPMENT - ANYTHING CAN BREAK - ANYTHING CAN CHANGE
+ Comments starting with # ~
+
+ In Vim script comments normally start with double quote. That can also be the
+ start of a string, thus in many places it cannot be used. In Vim9 script a
+ comment can also start with #. Normally this is a command to list text with
+ numbers, but you can also use `:number` for that. >
+ let count = 0 # number of occurences of Ni!
+
+
Vim9 functions ~
`:def` has no extra arguments like `:function` does: "range", "abort", "dict"

--- 250,258 ----
let var =234 " Error!
There must be white space before and after the "=": >
let var = 234 " OK
+ White space must also be put before the # that starts a comment: >
+ let var = 234# Error!
+ let var = 234 # OK
White space is required around most operators.
