I don't want my pager to clobber my terminal once I'm done looking at
whatever I was looking at.
This also means that I can remove its definition from the `batman`
script.
Using the `cppreference` package from the AUR, I can simply view them on
the go.
Installing `stdman` is pretty great too, replacing the awful Doxygen
auto-generated files for the standard library.
Switching to Termite because URxvt has weird rendering issues when
resizing the font.
i3-sensible-terminal needs the TERMINAL environment variable to launch
our prefered terminal emulator with the Ctrl+d binding.
Bash and Zsh both need a hook to enable Termite to open another terminal
in the same directory with the Ctrl+Maj+t binding.
