Hi,
I attached a new prompt_debian_setup and an RCS format diff between the
former one and this one.
The zstyle pattern now is :prompt:debian:${HOST-}:${USERNAME-}:${TERM-}:
in order to implement a variant of the suggested terminal blacklist in
future. The final : allows additional future extensions, if needed.
Additional configurable things would make the prompt more complex, thus
I skipped implementing them for now (the suggested ones and additional
ones can be implemented later). Franks other suggestions and some minor
changes are applied to the new prompt_debian_setup.
I think a recommended Debian .zshrc should also work on other systems,
at least in future releases of other Linux distributions. Therefore,
submitting this prompt_debian_setup upstream would be great, but only
a Debian zsh maintainer would be able to say "We plan to add this prompt
to the Debian zsh package and enable it in the recommended .zshrc for
new users. Please consider applying this patch.". According to the
channel topic, the zsh 5.0.9 release is expected to happen soonish.

This prompt color-scheme-able via zstyle. If the variabale TERM is set to
'dumb', colors are disabled, though. You can invoke the prompt thus:
prompt debian
TERM=dumb prompt debian
To configure the prompt's colors, this command can be used (don't forget to
run 'prompt debian' again to activate the changes):
zstyle ':prompt:debian:*' STYLE COLOR
You need to replace STYLE with 'dircolor', 'usercolor', 'usercolor-root',
'exitcolor' or 'exitcolor-root'. Valid values for COLOR include the numbers
from 0 to 7, 'black', 'red', 'green', 'yellow', 'blue', 'magenta', 'cyan' and
'white'.
Displaying version control information via vcs_info and displaying the name of
a Debian chroot is supported by this prompt, but only the latter is enabled by
default. To enable vcs_info with the user-context 'prompt_debian', run:
add-zsh-hook precmd prompt_debian_precmd_vcs_info
To disable vcs_info even if the vcs_info command is run, and to enable
it again, zstyle can be used as shown in the two lines below.
The other two lines enable checks for uncommited changes.
zstyle ':vcs_info:*' enable NONE
zstyle ':vcs_info:*' enable ALL
zstyle ':vcs_info:*' check-for-staged-changes true
zstyle ':vcs_info:*' check-for-changes true
To add additional information to the prompt, e.g., the history event number or
the number of background jobs and the shell level, this commands can be used.
The content of the 'nvcsformats' style is only shown if vcs_info is used, but
no version control system repository was found.
