+ When the option is a list of flags, {value} must be

+ Also see |:set-args| above.
+
+The {option} arguments to ":set" may be repeated. For example: >

+If you make an error in one of the arguments, an error message will be given

+ *:set-verbose*
+When 'verbose' is non-zero, displaying an option value will also tell where it

+ cindent ~
+ Last set from /usr/local/share/vim/vim60/ftplugin/c.vim line 30 ~
+This is only done when specific option values are requested, not for ":verbose

+When the option was set by hand there is no "Last set" message.
