Thank you Taylor and Jerome for your feedback. Because you brought up
some of the same issues I'll reply to you both here.

Yeah, if I want this file type plug-in included with the Vim runtime
files I'll probably have to disable the <F1> mapping by default because
it's already used by Vim. Note however that if the Lua Reference for Vim
isn't installed or no matching topic can be found then the mapping falls
back to Vim's default behavior (execute :help help.txt).

Because I wrote the file type plug-in for myself I didn't need any docs.
When I posted the plug-in to the list I added some in-line notes but
these aren't very useful to users of the plug-in. When I post the next
version to the list I will include documentation on how the features
provided by the plug-in can be used.

This functionality uses the matchit plug-in, which is included with Vim
but not enabled by default because of backwards compatibility with Vi.
The Vim docs explain how to enable the matchit plug-in, to read it
execute the following command from inside Vim: ":help matchit-install".

It should happen automatically if your Vim install supports automatic
commands and you have the luac program in your path. Since posting the
plug-in I've added some checks that make sure luac exists. Maybe the new
version would have given you an error message instead :).
It can already be disabled in the copy of the plug-in that I posted to
the list by setting the global variable 'lua_check_syntax' to zero:
let lua_check_syntax = 0
Maybe it would be better to disable this functionality by default and
let the user enable it when (s)he chooses to do so?

I agree with you that the automatic command shouldn't move the cursor
when luac isn't available or there are no errors. I've already fixed
this in my local copy. If you want to use the plug-in right now but
don't like this behavior see the note about the 'lua_check_syntax'
variable above.

I'm not sure I understand this. My visual cursor also jumps to the
status line when Vim is busy running automatic commands, but the cursor
returns to the buffer when the automatic commands finish. Does this not
happen for you or have I misunderstood you?

It appears I misunderstood the Vim docs when reading about text objects.
They are indeed repeatable. I'm working on making them so right now.

These are both bugs on my part. I've found getting the text objects to
work correctly is really hard, amongst other things because Lua
overloads 'end'.
I'll post an improved version of the plug-in to the list soon!
