broken syntax highlighting of bash

[xmlich02]

By the way, the trac version combobox doesn't allow selection of '4.8.20'.

Create an bash script:
#!/bin/bash
echo "hello world"
res="$(ls "-1" "$(pwd)")"
echo "hello world"

Second hello world is highlighted incorrectly. You can compare highlighting with vim or other editor as well. See attached screenshot
