Documented non-subexp option toggling

Regexp option toggling can be done in two forms:

/(?imx:subexpr)/ - this was already mentioned in docs
/before(?imx)after/ - there was no mention of this.

This section of the documentation could be improved further, see the following from the Onigmo docs:

    (?imxdau-imx)      option on/off
                         i: ignore case
                         m: multi-line (dot(.) match newline)
                         x: extended form

                       character set option (character range option)
                         d: Default (compatible with Ruby 1.9.3)
                            \w, \d and \s doesn't match non-ASCII characters.
                            \b, \B and POSIX brackets use the each encoding's
                            rules.
                         a: ASCII
                            ONIG_OPTION_ASCII_RANGE option is turned on.
                            \w, \d, \s and POSIX brackets doesn't match
                            non-ASCII characters.
                            \b and \B use the ASCII rules.
                         u: Unicode
                            ONIG_OPTION_ASCII_RANGE option is turned off.
                            \w (\W), \d (\D), \s (\S), \b (\B) and POSIX
                            brackets use the each encoding's rules.
