You mentioned in other mails that for testing, you're sourcing this file
multiple times. Since you can do this without error (e.g. redefining
functions without !, adding autocommands without clearing them first,
etc., are problematic if run twice) perhaps you don't the guard above
anyway. It won't matter if it's sourced twice. Also, since it doesn't
alter existing functionality (such as by mapping frequently used keys,
adding autocommands, changing highlighting, etc.) you may not need a way
to disable it (if you did, you would set loaded_HH in your .vimrc to
turn it off for a time).

Perhaps try to find the command which is causing messages to be output
and thereby triggering the 'Press Enter to Continue' message, and
prepend :silent to it.

No, it just doesn't allow for a bar ending a set command.

I think all that needs to change is line 293 of the vim.vim syntax file,
where the vimSet region end pattern needs to change from "$" to "|\|$".
That works for me. Chip/Bram, can you incorporate this?

Ben.
