.hgrc: Use pager
.oscrc: Add network:utilities in trusted projects
.Xresources: Add shift+up/down for moving one line up/down

Revert default shortcut (Alt+U) for selecting URLs
.gnupg/gpg-agent.conf: Use pinentry-gtk-2 as default

It falls back to pinentry-curses when no gui is available. I have created a
wrapper for gpg2 to use pinentry-curses when $GPG_TTY exists

.zsh/plugins/keychain.zsh: various/nothing produces no output, no need to
redirect to /dev/null
