Steps to reproduce

Latest upgrade of the runtime files brought in sh.vim version 205.
Unfortunately, it seems to be breaking sh/bash syntax highlight pretty badly for me.

On the left is sh.vim version 204, on the right is sh.vim version 205:

I was writing a few scripts, and every time, after a second or third command, the highlight was switching into shCmdSubRegion, covering everything.
On the picture that happened in line 3, and line 4 and below is all highlighted green.

Here is the test case from the picture:

#!/bin/bash

for name in {1..3}; do
  echo "$name"
done

Expected behaviour

Bash highlight works as before.
