This might (?) have made sense behind a firewall in 2003; but now it's
2018, the typical threat model that we are defending against has
changed from "vandals want to feel proud of their l33t skills"
to "organised crime wants your money", and a "trusted" local LAN
probably contains an obsolete phone, tablet, games console or
Internet-of-Things-enabled toaster with remote root exploits.
This make network topologies that used to be acceptable look
increasingly irresponsible.

With some fairly reasonable threat models (active or passive local
attacker able to eavesdrop on the network link, confidential
information being transferred via D-Bus), secure authentication is
insufficient to make this transport secure: it does not protect
confidentiality or integrity either.

These are like unix:tmpdir=/something, except that the resulting
socket is always path-based, never abstract.
This is desirable for two reasons:
* If a Linux container manager wants to expose a path-based socket
into the container, it can do so by bind-mounting it in the
container's filesystem namespace. That cannot work for abstract
sockets because they are not files.
* Conversely, if a Linux container manager does not want to expose
a path-based socket in the container, it can avoid bind-mounting it,
or bind-mount some harmless object like /dev/null over it.
That cannot work for abstract sockets because access to abstract
sockets is part of the network namespace, which is all-or-nothing.

Each U+002D HYPHEN-MINUS in [0-9A-Za-z_-/.\] is treated as a member of a
range. The third one, which appears to have been intended to be a
literal, is part of an empty range because the starting point
U+005F LOW LINE is greater than the endpoint U+002F SOLIDUS, resulting
in at least some grep implementations not considering U+002D, U+002F
or U+005F to match the pattern. This resulted in one of the
dbus-launch tests being unintentionally skipped when it used a
regex based on the one in the spec.
regex(7) suggests "To include a literal '-' [in a bracketed character
set], make it the first or last character".

For Unix, this partially duplicates the D-Bus Specification, but
provides more detail about the intention of each search path element.
It also documents the non-standardized path elements searched by the
reference implementation.
For Windows, there are no standardized path elements in the D-Bus
Specification (and it isn't clear how useful it would be to standardize
them, since Windows software that uses D-Bus tends to be installed
as an integrated "stack" with a bundled copy of a suitable dbus-daemon),
so we just document what the reference implementation does.
