Description

When upgrading vim to version 8 the syntax file does not work anymore:

line 16:
E10: \ should be followed by /, ? or &

I attached a file with the error log.

So the line continuation does not work, as vim is, no idea why, reading syntax files now in vi-compatible mode.
By looking inside other syntax files I noticed this is commonly handled by setting the nocompatible mode manually for that syntax file.

I attached also a patch fixing this issue.

Works fine here at least with the following vim's:

  • 8.0.670 on FreeBSD 12.2
  • 8.2.2029 as in macOS 11.6
  • 8.2.2434 as in Ubuntu 21.04

I can reproduce the logs provided with cpo manually set to vi-compatible mode or with C option added, but it works flawlessly out of the box.

It looks like in your particular setup cpo is garbled somewhere, might be in some other syntax file or in the configuration (compatible set?). Could you please check if it is indeed what happens?

It probably make sense to save cpo anyway, but I'm curios what actually causes the issue here.
