proposed addition to perlvar

Due to some [confusion a new user had][1] finding the documentation
for what $# does in $#foo, I suggest we add a small note to perlvar to
point people in the right direction (patch inlined).

diff --git a/pod/perlvar.pod b/pod/perlvar.pod

 Also see L<Error Indicators>.

+=item $#

+C<$#> is not a variable; it is a sigil like C<@> that can be prepended
+on the name of an array to get the index of the last item in that array.
+
+    my @a            = ("a", "b", "c");
+    my $last_index   = $#a;     # $last_index is 2
+    my $last_element = $a[$#a]; # $last_element is "c"
