// When adding an Ex command:
// 1. Add an entry to the table in src/nvim/ex_cmds.lua. Keep it sorted on the
// shortest version of the command name that works. If it doesn't start with
// a lower case letter, add it at the end.
//
// Each table entry is a table with the following keys:
//
// Key | Description
// ------- | -------------------------------------------------------------
// command | Name of the command. Required.
// enum | Name of the enum entry. If not set defaults to CMD_{command}.
// flags | A set of the flags from below list joined by bitwise or.
// func | Name of the function containing the implementation.
//
// Referenced function should be either non-static one or defined in
// ex_docmd.c and be coercible to ex_func_T type from below.
//
// All keys not described in the above table are reserved for future use.
//
// 2. Add a "case: CMD_xxx" in the big switch in ex_docmd.c.
// 3. Add an entry in the index for Ex commands at ":help ex-cmd-index".
// 4. Add documentation in ../doc/xxx.txt. Add a tag for both the short and
// long name of the command.
