+     '&' they want to be taken literally in the replacement and ensure
+     any instances of '&' they want to be replaced are unquoted.
+
+     For instance,
 
           var=abcdef
+          rep='& '
           echo ${var/abc/& }
           echo "${var/abc/& }"
-          echo ${var/abc/"& "}

-          echo ${var/abc/"\& "}
-
-     will display two lines of "abc def" and a third line of "& def".
-     The first two are replaced because the backslash is removed by
-     quote removal performed during the expansion of STRING (the
-     expansion is performed in a context that doesn't take any enclosing
-     double quotes into account, as with other word expansions).  In the
-     third case, the double quotes affect the expansion of '\&', and,
-     because '&' is not one of the characters for which backslash is
-     special in double quotes, the backslash survives the expansion,
-     inhibits the replacement, but is removed because it is treated
-     specially.  One could use '\\&', unquoted, as the replacement
-     string to achive the same effect.  It should rarely be necessary to
-     enclose only STRING in double quotes.

+          echo ${var/abc/"$rep"}
+
+     will display four lines of "& def".  Like the pattern removal
+     operators, double quotes surrounding the replacement string quote
+     the expanded characters, while double quotes enclosing the entire
+     parameter substitution do not, since the expansion is performed in
+     a context that doesn't take any enclosing double quotes into
+     account.
+
+     Since backslash can escape '&', it can also escape a backslash in
+     the replacement string.  This means that '\\' will insert a literal
+     backslash into the replacement, so these two 'echo' commands
+
+          var=abcdef
+          rep='\\&xyz'
+          echo ${var/abc/\\&xyz}
+          echo ${var/abc/$rep}
+
+     will both output '\abcxyzdef'.
+
+     It should rarely be necessary to enclose only STRING in double
+     quotes.

 This is intended to duplicate a common <code>sed</code> idiom.
-Backslash is used to quote &lsquo;<samp>&amp;</samp>&rsquo; in <var>string</var>; the backslash is removed
+</p>
+<p>Quoting any part of <var>string</var> inhibits replacement in the
+expansion of the quoted portion, including replacement strings stored
+in shell variables.
+Backslash will escape &lsquo;<samp>&amp;</samp>&rsquo; in <var>string</var>; the backslash is removed
 in order to permit a literal &lsquo;<samp>&amp;</samp>&rsquo; in the replacement string.
-Pattern substitution performs the check for &lsquo;<samp>&amp;</samp>&rsquo; after expanding
-<var>string</var>,
-so users should take care to quote backslashes intended to escape
-the &lsquo;<samp>&amp;</samp>&rsquo; and inhibit replacement so they survive any quote removal
-performed by the expansion of <var>string</var>.
-For instance,
+Users should take care if <var>string</var> is double-quoted to avoid
+unwanted interactions between the backslash and double-quoting, since
+backslash has special meaning within double quotes.
+Pattern substitution performs the check for unquoted &lsquo;<samp>&amp;</samp>&rsquo; after

+so users should ensure to properly quote any occurrences of &lsquo;<samp>&amp;</samp>&rsquo;
+they want to be taken literally in the replacement
+and ensure any instances of &lsquo;<samp>&amp;</samp>&rsquo; they want to be replaced are unquoted.
+</p>
+<p>For instance,
 </p>
 <div class="example">
 <pre class="example">var=abcdef
+rep='&amp; '
 echo ${var/abc/&amp; }
 echo &quot;${var/abc/&amp; }&quot;

-echo ${var/abc/&quot;\&amp; &quot;}
-</pre></div>
-
-<p>will display two lines of &quot;abc def&quot; and a third line of &quot;&amp; def&quot;.
-The first two are replaced because the backslash is removed by quote
-removal performed during the expansion of <var>string</var>
-(the expansion is performed in a
-context that doesn&rsquo;t take any enclosing double quotes into account, as
-with other word expansions).
-In the third case, the double quotes affect the expansion
-of &lsquo;<samp>\&amp;</samp>&rsquo;, and, because &lsquo;<samp>&amp;</samp>&rsquo; is not one of the characters for
-which backslash is special in double quotes,
-the backslash survives the expansion, inhibits the replacement,
-but is removed because it is treated specially.
-One could use &lsquo;<samp>\\&amp;</samp>&rsquo;, unquoted, as the replacement string to achive
-the same effect.

+<p>will display four lines of &quot;&amp; def&quot;.
+Like the pattern removal operators, double quotes surrounding the
+replacement string quote the expanded characters, while double quotes
+enclosing the entire parameter substitution do not, since
+the expansion is performed in a
+context that doesn&rsquo;t take any enclosing double quotes into account.
+</p>
+<p>Since backslash can escape &lsquo;<samp>&amp;</samp>&rsquo;, it can also escape a backslash in
+the replacement string.
+This means that &lsquo;<samp>\\</samp>&rsquo; will insert a literal
+backslash into the replacement, so these two <code>echo</code> commands
