* invoke.texi: Ensure that the option lists fit within the
margins of a PDF page. Re-worded description of
'-ffrontend-loop-interchange' so that it fits with the margins
of a PDF page. Add '-fdec-include', '-fdec-blank-format-item'
and '-fdec-format-defaults' to list of options that are enabled
by '-fdec'.
