[Dbix-class] patch: escaping user input - cookbook example

[Carl Franks]

Here's a minor patch to address an issue that I found a solution for
in the list archives, but couldn't find in the docs anywhere.

It's against http://dev.catalyst.perl.org/repos/bast/DBIx-Class/0.08/trunk
if it should be against a different location and doesn't patch
cleanly, let me know and I'll fix it.

Cheers,
Carl

+=head2 Escaping user input
+
+If you need to insert user input into a string before passing it to
+L<DBIx::Class>: for example, to use the input string C<$query> in a
+wildcard search C<%$query%>, then use the following construction.
+
+  my $rs = $schema->resultset('Foo')->search(
+      {
+        name => \'LIKE ?',
+      },
+      {
+        bind => [ "%$query%", $query ],
+      }
+  );
