Indrajit Raychaudhuri 17a59bada7 [prompt] Rename helper function promptpwd to prompt-pwd for consistency
Changes:
* In prezto, function names are hyphenated ('-') by convention,
  rename `promptpwd` to `prompt-pwd` accordingly.
* Unset local variable `current_pwd` proactively.
* Tweak additional documentation for `prompt-pwd`.

### 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.
