[prompt] Rename helper function promptpwd to prompt-pwd for consistency

Browse Source 
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`.
