flake8 pointed out that some regexes in the pretty-printers are
missing a backslash. This patch fixes these.
libstdc++-v3/ChangeLog:
* python/libstdcxx/v6/printers.py
(StdExpAnyPrinter.__init__, StdExpOptionalPrinter.__init__):
Add missing backslash.
* python/libstdcxx/v6/xmethods.py
(ArrayMethodsMatcher.match, DequeMethodsMatcher.match)
(ForwardListMethodsMatcher.match, ListMethodsMatcher.match)
(VectorMethodsMatcher.match)
(AssociativeContainerMethodsMatcher.match)
(UniquePtrGetWorker.__call__, UniquePtrMethodsMatcher.match)
(SharedPtrSubscriptWorker.__call__)
(SharedPtrMethodsMatcher.match): Add missing backslash.
