Replacement text ~
+ The {repl} argument is normally one long string, possibly with "|" separated
+ commands. A special case is when the argument is "{", then the following
+ lines, up to a line starting with "}" are used and |Vim9| syntax applies.
+ Example: >
+ :command MyCommand {
+ echo 'hello'
+ g:calledMyCommand = true
+ }
+ No nesting is supported.
+
The replacement text {repl} for a user defined command is scanned for special
escape sequences, using <...> notation. Escape sequences are replaced with
values from the entered command line, and all other text is copied unchanged.

Vi is clearly superior to emacs, since "vi" has only two characters
(and two keystrokes), while "emacs" has five. (Randy C. Ford)
