### TODO XXX
|
|
|
# This section exists to patch over vulnerabilities when sourcing the
|
|
|
# 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.
