Andrew Eikum 16dad32e43 Reword sentences that contain psuedo-English "resp." 
As you likely know, Arch Linux is in the process of moving to systemd.
So I was reading through the various systemd docs and quickly became
baffled by this new abbreviation "resp.", which I've never seen before
in my English-mother-tongue life.

Some quick Googling turned up a reference:
<http://www.transblawg.eu/index.php?/archives/870-Resp.-and-other-non-existent-English-wordsNicht-existente-englische-Woerter.html>

I guess it's a literal translation of the German "Beziehungsweise", but
English doesn't work the same way. The word "respectively" is used
exclusively to provide an ordering connection between two lists. E.g.
"the prefixes k, M, and G refer to kilo-, mega-, and giga-,
respectively." It is also never abbreviated to "resp." So the sentence
"Sets the default output resp. error output for all services and
sockets" makes no sense to a natural English speaker.

This patch removes all instances of "resp." in the man pages and
replaces them with sentences which are much more clear and, hopefully,
grammatically valid. In almost all instances, it was simply replacing
"resp." with "or," which the original author (Lennart?) could probably
just do in the future.

The only other instances of "resp." are in the src/ subtree, which I
don't feel privileged to correct.

<title>Description</title>
<para>The <filename>/etc/os-release</filename> file
contains operating system identification data.</para>
<para>The basic file format of
<filename>os-release</filename> is a newline-separated
list of environment-like shell-compatible variable
assignments. It is possible to source the
configuration from shell scripts, however, beyond mere
variable assignments no shell features are supported
(this means variable expansion is explicitly not
supported), allowing applications to read the file
without implementing a shell compatible execution
engine. Variable assignment values should be enclosed
in double or single quotes if they include spaces,
semicolons or other special characters outside of A-Z,
a-z, 0-9. All strings should be in UTF-8 format, and
non-printable characters should not be used. If double
or single quotes or backslashes are to be used within
variable assignments they should be escaped with
backslashes, following shell style. It is not
supported to concatenate multiple individually quoted
strings. Lines beginning with "#" shall be ignored as
comments.</para>
<para><filename>/etc/os-release</filename> contains
data that is defined by the operating system vendor
and should not be changed by the administrator.</para>
<para>As this file only encodes names and identifiers
it should not be localized.</para>
<para>The file <filename>/etc/os-release</filename> might
be a symlink to another file, but it is important that
the file is available from earliest boot on, and hence
must be located on the root file system.</para>
<para>For a longer rationale for
<filename>/etc/os-release</filename> please refer to

<listitem><para>A string identifying
the operating system, without a

<listitem><para>A string identifying
the operating system version,
excluding any OS name information,
possibly including a release code

optional. Example:
<literal>VERSION=17</literal> or
<literal>VERSION="17 (Beefy

<varlistentry>
<term><varname>ID=</varname></term>
<listitem><para>A lower-case string

</varlistentry>
<varlistentry>
<term><varname>ID_LIKE=</varname></term>
<listitem><para>A space-separated list
of operating system identifiers in the
same syntax as the
<varname>ID=</varname> setting. Should
list identifiers of operating systems
that are closely related to the local
operating system in regards to
packaging and programming interfaces,
for example listing one or more
OS identifiers the local
OS is a derivative from. An
OS should generally only list other OS
identifiers it itself is a derivative
from, and not any OSes that
are derived from it, but symmetric
relationships are possible. Build
scripts and similar should check this
variable if they need to identify the
local operating system and the value
of <varname>ID=</varname> is not
recognized. Operating systems should
be listed in order of how closely the
local operating system relates to the
listed ones, starting with the
closest. This field is
optional. Example: for an operating
system with
<literal>ID=centos</literal> an
assignment of <literal>ID_LIKE="rhel
fedora"</literal> would be
appropriate. For an operating system
with <literal>ID=ubuntu</literal> an
assignment of
<literal>ID_LIKE=debian</literal> is
appropriate.</para></listitem>

should refer to the homepage of the
operating system, or alternatively
some homepage of the specific version

should refer to the main support page
for the operating system, if there is
any. This is primarily intended for
operating systems which vendors
provide support
for. <varname>BUG_REPORT_URL=</varname>
should refer to the main bug reporting
page for the operating system, if
there is any. This is primarily
intended for operating systems that
rely on community QA. These settings
are optional, and providing only some
of these settings is common. These

"About this system" UIs behind links
with captions such as "About this
Operating System", "Obtain Support",

<literal>http:</literal> or
<literal>https:</literal> URLs, and
possibly <literal>mailto:</literal> or
<literal>tel:</literal>. Only one URL
shall be listed in each setting. If

</variablelist>
<para>If you are reading this file from C code or a
shell script to determine the OS or a specific version
of it, use the ID and VERSION_ID fields, possibly with
ID_LIKE as fallback for ID. When looking for an OS
identification string for presentation to the user use
the PRETTY_NAME field.</para>
<para>Note that operating system vendors may choose
not to provide version information, for example to
accommodate for rolling releases. In this case VERSION
and VERSION_ID may be unset. Applications should not
rely on these fields to be set.</para>
<para>Operating system vendors may extend the file
format and introduce new fields. It is highly
recommended to prefix new fields with an OS specific
name in order to avoid name clashes. Applications
reading this file must ignore unknown fields. Example:
<literal>DEBIAN_BTS="debbugs://bugs.debian.org/"</literal></para>
