Adjust instruction for setting custom `$ZDOTDIR`.
This addresses 2 potential issues:
- Check for the presence of `$XDG_CONFIG_HOME/zsh` before assigning it to `$ZDOTDIR` instead of blindly assigning
- Avoid recursion in zsh variable assignment stack that might occasionally result in messages like:
```
zsh: job table full or recursion limit exceeded
```
The startup logic and instructions have been updated for simplicity in
pyenv 2.3.0. The workaround for pyenv init is no longer necessary.

The desired logic is:
For the `pyenv` plugins `virtualenv-init` and `virtualenvwrapper`:
1. If either plugin is present, activate it
2. If `virtualenvwrapper` plugin is not present, then
[fallback to standard
`virtualenvwrapper`](https://github.com/sorin-ionescu/prezto/pull/1414#issuecomment-320306421).
3. If `virtualenvwrapper` plugin is present, then [don't fallback to
standard `virtualenvwrapper`, regardless of whether `virtualenv-init`
is
present](https://github.com/sorin-ionescu/prezto/pull/1981#issue-1123766676).
Previously, if the `virtualenv` command was present but `pyenv` was
missing, then the fallback wouldn't be hit. This bug was introduced by
https://github.com/sorin-ionescu/prezto/pull/1981/ which ensured that
the `pyenv` `virtualenvwrapper` plugin was activated if present,
regardless of the presence of the `virtualenv-init` plugin.
As an optimization, the check for the `pyenv` plugins are skipped if
`pyenv` itself isn't found.
Since we only want to fallback if the `pyenv` `virtualenvwrapper` plugin
is missing, but that's buried within the `pyenv` logic and we also need
to handle when `pyenv` itself is missing, this switches to using a flag
variable.
I also renamed the `virtualenv_sources` var to
`virtualenvwrapper_sources` as `virtualenv` is distinct from
`virtualenvwrapper`, so using one name for a var that is really about
the other is confusing.
Looking at `git blame`, there's a _lot_ of prior art here around trying
to support all the permutations of `pyenv` and various plugins:
* https://github.com/sorin-ionescu/prezto/issues/1413
* https://github.com/sorin-ionescu/prezto/pull/1414
* https://github.com/sorin-ionescu/prezto/pull/1433
* https://github.com/sorin-ionescu/prezto/pull/1434
So we need to be extremely careful to continue to support all these
permutations.
Fix https://github.com/sorin-ionescu/prezto/issues/2022
This is needed to find python.
It is often already set because a user has the directory or completion module loaded before this, but that's not always true.
See extensive debugging / further explanation here: https://github.com/sorin-ionescu/prezto/issues/1949
This does not fully resolve that issue, as there's another enhancement that I'll put up as a separate PR.
In most systems, python2 or python3 command/soft-link would almost
always exist. In such cases, we don't need to invoke `python` to
detect the version. This should speed things up a bit as well.
Docker For Mac has broken support for `docker-compose`.
Since `docker compose` is a drop in replacement and it Just Works™, this PR converts `docker-compose` to `docker compose`
While previusly configurable, it was inconsistent with other
configuration options and it was missing configurability of in memory /
on disc history size.

Two additional sets of paths are now added to the default list of well
known paths: '$HOME/{bin,sbin}' and '/opt/{homebrew,local}/{bin,sbin}'.
- '$HOME/{bin,sbin}': Most users have custom scripts in '$HOME/bin'
anyway, we might as well honor those. '$HOME/sbin' is not really common,
but we can keep it for consistency.
- '/opt/{homebrew,local}/{bin,sbin}': With Homebrew changing default
installation location in macOS on Apple Silicon which will eventually
become ubiquitous, we have a good reason to add these paths by default.
While at it, we also honor MacPorts installation.
In all cases, we add them _iff_ the paths actually exist, not otherwise.
This has the side effect of a newly installed program not available
immediately in the '$path' in a mint fresh system (because of the fact
that '/opt/{homebrew,local}/{bin,sbin}' won't exist initially) until the
shell is reloaded. But that's a minor inconvenience to keep the '$path'
from getting unnecessarily bloated.
For performance reasons, we prefer detecting Homebrew prefix internally
instead of the more idiomatic form `brew --repository`.
We attempt looking up $HOMEBREW_REPOSITORY first (in case `brew shellenv`
has been sourced-in earlier). Else, we look it up by resolving absolute
path of $HOMEBREW_REPOSITORY.
This should work for most standard (and officially documented) Homebrew
installations.

same as $HOMEBREW_REPOSITORY except when Homebrew is installed in
'/usr/local' ($HOMEBREW_REPOSITORY == '/usr/local/Homebrew'). This is
usually the case for Intel Macs.
