+    # file in $_prompt_sorin_precmd_async_data. Without it if a branch is named
+    # $foo it will expand if we have a $foo variable, and a branch named
+    # $(IFS=_;cmd=rm_-rf_~;$cmd) could delete the users home directory.
+    # This is a stopgap to prevent code execution and fix the vulnerability,
+    # but it eventually needs to be removed in favor of zsh_async and not using
+    # a file to store the prompt data in.
