Change use of deprecated '->' operator on an iterator

Browse Source 
In display_buffer.hh, the '->' operator is used on an iterator, but
(surprisingly) this is deprecated from C++20 because of x-value vs
l-value ambiguity. Now clang's -Wdeprecated-declarations warns about it
as we declare -std=c++2a. See

which was adopted for 2019-03.
