Fixes #10751

Fixes #10744

When the `git init` call fails, the directory is not created,
so the rm command fails with a not found error. This change
checks whether the directory exists before deleting it.

The previous check simply compared whether the last commit of the branch
was the same in the local and the remote repository.

This commit also checks whether the remote commit is an ancestor of the
local commit. This fixes the case where the local repository has new
commits after the last published commit.

Fixes #10680

BREAKING CHANGE: the `copydir` plugin is deprecated. Instead of
using `copydir`, use `copypath` which also supports copying
the path of other files or directories specified.

Closes #7569
Closes #10714

This lib function applies a patch to the VCS_INFO_formats function
in zsh versions from v5.0.3 until v5.8, which don't quote % chars
in some arguments received. Normally that just means that some
% characters in these strings (branch names, directories, etc.)
will be incorrectly parsed as formatting sequences.

With CVE-2021-45444, however, this means that one of these strings
from a malicious source (e.g. a malicious git repository) can
trigger command injection and run arbitrary code in the user's
machine when visiting such git repository.

Zsh 5.8.1 fixes this vulnerability [1], but older vcs_info setups
still need a workaround such as this one to patch the vulnerability.

BREAKING CHANGE: some aliases have been renamed to be consistent with the rest.
Mainly, aliases for `juju show-` commands are renamed to `jsh*`. This also means
that `jsh` and `jshc` have been renamed to `jssh` and `jsshc`. Have a look at the
README for the complete alias changes.

BREAKING CHANGE: `wjst` will no longer show storage in the status
output. This is done for consistency with the `jst` and `jsts`
aliases.

Fixes #9699

Takes into account $ZLE_RPROMPT_INDENT and doesn't add the extra
space at the end so it doesn't bleed into the next line.
