-The back-reference <SAMP>`\<VAR>n</VAR>'</SAMP>, where <VAR>n</VAR> is a
single digit, matches
-the substring previously matched by the <VAR>n</VAR>th parenthesized
subexpression
-of the regular expression. For example, <SAMP>`(a)\1'</SAMP> matches
<SAMP>`aa'</SAMP>.
-When use with alternation if the group does not participate in the match, then
-the back-reference makes the whole match fail. For example,
<SAMP>`a(.)|b\1'</SAMP>
-will not match <SAMP>`ba'</SAMP>. When multiple regular expressions are given
with
-<SAMP>`-e'</SAMP> or from a file <SAMP>`-f file'</SAMP>, the back-referecences
are local to
-each expression.
