According to the following comment in ex_docmd.c:
/*
* If the command was typed, remember it for the ':' register.
* Do this AFTER executing the command to make :@: work.
*/
The ":" register is set after executing the command. So in the above autocmd,
the ":" register will not contain the current command.
