The vim docs give me the impression that individual autocommands are

This sequence of autocommands:
autocmd BufWritePost * if 0 | echo <afile> | endif
autocmd BufWritePost * echo "foo"
will not cause "foo" to be echoed when a buffer is written.
Reversing the order of the above two autocommands will result in "foo"
being echoed.
The <afile> reference is the part of the first autocommand that must be
present to cause this problem.

I get error E15 when trying to trigger an autocommand for
echo <afile>
but
echo expand('<afile>')
(still in an autocommand) gives the desired result.
See :help expand()
and, for the doubled single quotes between single quotes: :help
literal-string
IIUC, the reason for the E15 is that <afile> is only expanded in
ex-commands at places where a *file name* is expected. The operand
expected by :echo is not an (unquoted) filename but an expression.
In your example, the syntax error may prevent the endif clause from
being recognised, thus putting the «echo "foo"» inside the
never-executed true branch of «if 0».
Best regards,
Tony.
