patch 8.2.1549: "r" fails if 'esckeys' is off and modifyOtherKeys is used

Problem:    The "r" command fails for keys with modifiers if 'esckeys' is off
            and modifyOtherKeys is used. (Lauri Tirkkonen)
Solution:   Temporarily disable bracketed paste and modifyOtherKeys if
            'esckeys' is off. (closes #6809)
