Entirely zstyle-configured prompt.
:prompt:zstyle {ps{1,2,3,4},rps{1,2}} is used as the specification,
each part of those arrays is either found in :prompt:zstyle:parts or
:prompt:zstyle:default:parts, or it's set as is. This means you can
put bare strings in there, like ' ' or '%~', and customize various parts
by setting them under :prompt:zstyle:parts.
If you enable this prompt with a preset, it will set some styles for you
in accordance with the preset. Available presets are:
* fish (like the fish shell)
To completely reset user customizations (except stuff under :defaults),
run prompt_zstyle_reset.
Note that it's up to you to configure vcs_info.
The default vcsinfo part simply prints ${vcs_info_msg_0_}.
Some presets will prepend it with a space (if non-null only).
Promptsubst is enabled, so you can have function calls in your custom parts.
