Closes #9396

This is an improvement (in my opinion) to the `brews` command that prints each leaf formula (in white), followed by its dependencies (in blue), on each line. Compared to the existing flat list of formulae, the new layout is both more compact and more informative, by differentiating leaves from dependencies at a glance.

Closes #8912

Added the red dot (instead of the default `*`) if the branch is dirty.

The bira theme only supported git, now it supports mercurial as well. It
needed ito call `hg_prompt_info` and the `ZSH_THEME_HG_PROMPT_`
variables.

Closes #6631

BREAKING CHANGE: the `hg_prompt_info` function now uses `ZSH_THEME_HG_PROMPT_PREFIX`
and `ZSH_THEME_HG_PROMPT_SUFFIX` variables when displaying branch information, similar
to the `git_prompt_info` function.

Closes #6631

Replaced two different calls of hg with one `hg --id --branch` for retrieving
information whether we're in a repo (will be empty if not), whether the repo is
dirty (revision id will contain "+" if there are uncommitted changed), and the
branch name.
