Output of :set termcap is below. More details about reproducing this:
This happens to me on the konsole with (1) white-on-black konsole
schema and (2) no blinking cursor. Maybe this is konsole problem.
I get matchparen display wrong in the following scenario:
1. In konsole, disable blinking cursor. Set 'White on Black' konsole schema.
2. cp /dev/null /tmp/.vimrc # simulate empty .vimrc
3. HOME=/tmp TERM=xterm-mono vim
