Subject: [PATCH] Ensure older vims process buffer at startup

In this context older vims are those without timer_start() and lambda.

The plugin always used to process the buffer at startup.  Then in #734
an optimisation was introduced to defer processing at startup, to keep
vim's startup fast.  However in this optimisation older vim's
unintentionally lost their startup processing altogether.
