 Bash 1.14 from 1992 incorrectly fails this test. This was fixed for Bash 2.0 in 1996:
 
-    var='!'
-    [ "$var" = "!" ]
+```sh
+var='!'
+[ "$var" = "!" ]
+```
 
 Dash 0.5.4 from 2007 incorrectly passes this test. This was fixed for Dash 0.5.5 in 2008: 
 
-    x='(' y=')'
-    [ "$x" = "$y" ]
+```sh
+x='(' y=')'
+[ "$x" = "$y" ]
+```
 
 Zsh (while not supported by ShellCheck) fixed the same problem in 2015.
