~/.zshrc: Use bold for failed/aborted commands.

It still has that weird bug where part of the command is repeated in
front of the actual command.

Any pointers welcome. Pointers will get a grateful email or something.
Or commit dedicated to them.

.zshrc

	user="%{$fg[red]%}%n%{$reset_color%}"
	dir="%{$fg[cyan]%}%~%{$reset_color%}"
	lastcmd="$history[$(($HISTCMD-1))]"
	lastcmd_witherror="%(?.$lastcmd.%S$lastcmd%s)"
	lastcmd_witherror="%(?.$lastcmd.%B$lastcmd%b)"
	PROMPT="$user in $dir@$(repo_branch) $lastcmd_witherror
$(repo_char) $ "
	RPROMPT="%D{%Y-%m-%d} %{$fg[red]%}%t%{$reset_color%}"
