For a global option the global value is
shown (but that might change in the future).
-:setl[ocal] {option}< Set the local value of {option} to its global value by
- copying the value.
+:se[t] {option}< Set the effective value of {option} to its global
+ value.
+ For string |global-local| options, the local value is
+ removed, so that the global value will be used.
+ For all other options, the global value is copied to
+ the local value.
-:se[t] {option}< For |global-local| options: Remove the local value of
- {option}, so that the global value will be used.
+:setl[ocal] {option}< Set the effective value of {option} to its global

+ For number and boolean |global-local| options, the
+ local value is removed, so that the global value will
+ be used.
+ For all other options, including string |global-local|
+ options, the global value is copied to the local
+ value.
+
+Note that the behaviour for |global-local| options is slightly different
+between string and number-based options.
