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.

We attempt looking up $HOMEBREW_PREFIX or $HOMEBREW_REPOSITORY first (in
case `brew shellenv` has been sourced-in earlier). Else, we look it up
by resolving absolute path of $HOMEBREW_REPOSITORY. $HOMEBREW_PREFIX is
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.
This should work for most standard (and officially documented) Homebrew
installations.
